How to manage multiple eSIMs on your smartphone?
With the democratization of eSIMs, it is now possible to use multiple mobile lines on the same device, without having to handle physical cards. This technological advancement offers unprecedented flexibility, especially for frequent travelers, professionals, or anyone needing multiple plans. How to install, manage, and switch between multiple eSIMs? We explain.
What is an eSIM?

An eSIM, or « embedded SIM », is a virtual SIM card integrated directly into a smartphone or other connected device. It requires no manual insertion or handling, unlike traditional physical SIM cards. Everything is done digitally: activation, deletion, or even changing operators.

eSIMs function like traditional SIM cards, allowing identification with a mobile network and access to phone and internet services. The main difference lies in their flexibility: you can store multiple eSIM profiles on the same device and switch between them as needed.

How to install multiple eSIMs?

If you travel to different countries or need multiple mobile lines, installing several eSIMs is an excellent option. Here’s how to do it:

1. Check your device’s compatibility

Not all smartphones are eSIM compatible. To check if yours is:
- Go to Settings > Mobile Data.
- If the « Add eSIM » option is available, your device is compatible.
- You can also dial *#06# to display the EID (eSIM identifier) number.
2. Purchase an eSIM

You can purchase an eSIM from an operator or a provider like Vostra.world. Depending on your destination, you’ll have the choice between local, regional, or global plans.

3. Install an eSIM

Once your eSIM is purchased, you will receive a QR code or an activation code:
- Open Settings > Mobile Network > Add eSIM.
- Scan the QR code or enter the activation code.
- Follow the instructions to complete the installation.
How to switch between eSIMs?

Once multiple eSIMs are installed, you can easily switch between them:
- Go to Settings > SIM Cards & Mobile Networks.
- Select the eSIM you want to activate.
- Deactivate the previous eSIM if necessary.
This feature is particularly useful for travelers who wish to use a local eSIM while keeping their main line active.

How many eSIMs can I add to my phone?
- iPhone: Up to five eSIMs can be stored, but only two can be active simultaneously.
- Android (Samsung, Google, Huawei): On average, five to seven eSIMs can be installed, with only one active at a time.
The advantages of having multiple eSIMs

Using multiple eSIMs offers several advantages:
- Avoid roaming charges by activating a local eSIM in each country.
- Switch between a business line and a personal line.
- Store multiple plans without having to handle physical SIM cards.
Can an eSIM be used with a physical SIM card?

Yes, most modern smartphones support Dual SIM mode, allowing you to use an eSIM and a physical SIM card simultaneously. Here are some examples of use:
- Use an eSIM for mobile data and a physical SIM for calls.
- Have a local line for work and another for personal contacts.
In your phone’s settings, you can assign a specific eSIM for calls, another for SMS, and yet another for mobile data.

When and how to delete an eSIM?

If you no longer wish to use an eSIM, here’s how to delete it:
- Go to Settings > SIM Cards & Mobile Networks.
- Select the relevant eSIM and tap « Delete ».
It’s also possible to temporarily deactivate an eSIM if you plan to use it later.

Managing multiple eSIMs is a real asset for travelers and professionals. Thanks to Vostra.world, you can access flexible and optimized plans for your daily use.

How to track and recharge your data with an eSIM
When traveling abroad, it’s essential to know how much mobile data you’ll consume. This helps you choose an eSIM plan that fits your needs and avoid unpleasant surprises. This guide will help you estimate your consumption, understand how mobile data works, and provide practical tips for using less.
What is mobile data?

Mobile data refers to information exchanged between your phone and the Internet via a cellular network (3G, 4G, 5G), without using Wi-Fi.

When you use the Internet without being connected to a Wi-Fi network, you consume mobile data. With an eSIM, this connection is made directly via the local mobile network of the country you’re visiting.

Difference between Wi-Fi and mobile data

Wi-Fi relies on a signal emitted by a local router, usually free or included with accommodation. Mobile data, on the other hand, uses a telecom operator’s network.

The advantage of mobile data is that it allows you to access the Internet everywhere, without depending on an access point. However, it can incur additional costs if you exceed your quota or are roaming.

What uses consume the most data?

The amount of data consumed depends on the applications used and the type of content loaded. Here’s an indicative estimate of consumption per activity:
- Google Maps: ~5 MB/hour
- Social networks (photos, short videos): ~50 MB/hour
- Standard web browsing: ~50 MB/hour
- Online games: ~70 MB/hour or more
- Music streaming: ~100 MB/hour
- Video in SD quality: ~1 GB/hour
- Video in HD: ~4 GB/hour
- Video in 4K: ~7 GB/hour
How much eSIM data do I need?

1 GB of data allows for approximately 20 to 30 minutes of daily use for browsing, emails, and social networks. If you primarily use the card for communication, 1 to 3 GB per week may suffice. However, for frequent streaming or video calls, plan for a volume between 5 and 10 GB.

For a two-week stay in France with moderate usage, a 3 GB plan valid for 15 days is generally sufficient. Vostra offers flexible eSIMs for every destination.

How to track my eSIM data usage?

On iPhone, you can add a tracking widget. It shows you the remaining data in real time. You can also receive alerts via push notifications.
- iPhone: Settings > Notifications > Vostra App > Allow Notifications
- Android: Settings > Notifications > App settings > Vostra
How to top up my eSIM data?

If you have a top-up plan, log in to your Vostra eSIM app, go to « My eSIMs, » select your plan, and choose « Top Up. » If the option doesn’t appear, it means the plan is not top-upable, and you’ll need to purchase a new one.

Now, if you choose to disable mobile data, you must connect to Wi-Fi to access the Internet. This can be useful for saving your quota, but be careful not to be without access if you are traveling without a secure Wi-Fi network.

5 practical tips to reduce your data consumption while traveling

Here are 5 concrete tips to use your eSIM more intelligently and extend your plan’s duration.

1. Block background data usage

Many applications continue to consume data, even when you are not actively using them. This is the case for social networks, messaging apps, weather apps, and emails that synchronize automatically. To prevent this, disable background app refresh in your phone settings.

On iPhone: Settings > General > Background App Refresh.

On Android: Settings > Connections > Data Usage > Background data.

By blocking these invisible uses, you will drastically reduce your consumption without compromising the user experience.

2. Activate « Low Data Mode » on iPhone or « Data Saver » mode on Android

« Low Data Mode » is designed to limit the amount of data your iPhone uses. It automatically suspends certain features like automatic updates, iCloud backups, or photo uploads. This is particularly useful when traveling with a limited plan.

How to activate it: Settings > Cellular Data > eSIM Line > Low Data Mode.

On Android, « Data Saver » mode acts similarly. It prevents applications from receiving or sending data when they are not active.

To activate it on Samsung: Settings > Connections > Data Usage > Data Saver.

On standard Android: Settings > Network & Internet > Data Usage > Data Saver.

Result: you stay connected, but your data is reserved only for priority tasks 😇.

3. Download your maps in advance

Using Google Maps or other online navigation apps can consume a lot of data, especially on long journeys. A simple trick is to download maps of your destination before you leave. How to do it? Open the app with a Wi-Fi connection, search for the desired area, and tap « More » > « Download offline map. »

4. Store music, videos, and podcasts in advance

Streaming is one of the most data-intensive uses of mobile data. A YouTube HD video can consume between 1 and 4 GB per hour. To avoid this, download your content in advance via Wi-Fi: Spotify playlists, Netflix series, podcast episodes… Once downloaded, this content will be accessible offline, with no additional charges.

5. Disable Wi-Fi Assist

Wi-Fi Assist is a feature that automatically switches to mobile data as soon as the Wi-Fi connection is deemed unstable. This can lead to unintentional consumption, especially in hotels, cafes, or train stations where Wi-Fi is sometimes slow or intermittent.

On iPhone: Settings > Cellular Data > Disable “Wi-Fi Assist”.

On Android: Settings > Network > Wi-Fi > Advanced settings > Disable automatic switch to mobile network.
Once disabled, your device will remain connected to Wi-Fi, even if the signal quality temporarily drops.

FAQ

How do I know how much data I need during my trip?

Start by estimating your daily usage (browsing, social networks, streaming, GPS). For example, if you mainly use the Internet for emails and Google Maps, 1 to 3 GB is enough for a week. For regular video or audio streaming, plan for at least 5 to 10 GB. The article details average consumption per activity to help you.

Why does my data run out quickly even though I’m not actively using the Internet?

Applications can use data in the background (automatic updates, cloud synchronization, content refresh). Remember to disable these functions in the settings and restrict data access to only essential apps when you are abroad.

What happens if I disable my mobile data during my trip?

By disabling mobile data, your device will only be able to access the Internet via Wi-Fi. This helps save your plan but can be inconvenient if you are traveling and don’t have Wi-Fi available. The ideal is to activate data only when you need it.

Traveling with an eSIM: what you need to know
Traveling with an eSIM means enjoying an immediate mobile connection, without a physical card or roaming charges. But what happens when you change countries? Do you need to buy a new eSIM at each border? In this article, we clearly explain the differences between local, regional, and global eSIMs to help you choose the right plan for your itinerary.

How does an eSIM work abroad?

An eSIM (virtual SIM) allows you to connect to a local mobile network without needing a physical SIM card. When traveling abroad, this prevents you from having to use your usual operator’s expensive roaming plans.

Specifically, you download an eSIM profile corresponding to your destination and you’re connected to a local operator as soon as you arrive. In other words, you have access to internet, calls, and SMS at local rates, without extra roaming charges. Practical, economical, and activatable in just a few minutes.

Using a Vostra eSIM in another country: what you need to know

A question that often comes up among our users is: is it possible to use a Vostra eSIM abroad? The answer depends on the type of plan you choose. At Vostra, we offer three types of eSIM plans: local, regional, and global. The choice of your eSIM will therefore depend on your destination and your connectivity needs.

What is a local eSIM?

A local eSIM is valid in a single country. It’s ideal if you plan to stay in the same destination. For example, if you’re traveling in France, you can buy a French eSIM that will work anywhere in the country, whether you’re in Paris, Marseille, or Lilles.

Once activated, this eSIM connects to a French operator, offering you an experience identical to that of a resident. However, if you leave the country, you’ll need to install a new eSIM adapted to your next destination.

What is a regional eSIM?

Regional eSIMs cover several countries within the same geographical area. This is a suitable solution if you are planning a multi-country itinerary within the same region (Europe, Asia, etc.).

For example: you depart from Côte d’Ivoire, pass through Mali, then Senegal. Rather than buying an eSIM for each country, you opt for a regional eSIM for Africa, which will work in all these territories. You thus remain connected without interruption throughout your trip.

Some examples of areas covered by regional eSIMs:
- Africa
- Asia
- Australia and Oceania
- Caribbean
- Europe
- Latin America
- Middle East and North Africa
- North America
What is a global eSIM?

The global eSIM is the most flexible solution for globetrotters. It works in several regions and countries simultaneously. If you’re embarking on a long journey covering Europe, Asia, and America, for example, you only need one global eSIM plan to stay connected throughout the trip.

This type of eSIM is perfect for digital nomads, backpackers, or anyone who frequently changes countries. It avoids repeated installations and offers a seamless experience, even when traveling intercontinentally.

FAQ

Does my eSIM work automatically in all countries?

No. Coverage depends on the type of plan you’ve chosen: local (1 country), regional (several countries in the same zone), or global (multi-regions). Always check the list of included countries before purchasing.

Do I need to buy a new eSIM every time I change countries?

Not necessarily. If you have a local eSIM, yes. However, regional or global plans allow you to stay connected in several countries without interruption.

How do I activate a Vostra eSIM abroad?

Once your eSIM is purchased on Vostra.world, you will receive a QR code. Scan it from your smartphone settings, then activate the eSIM in a few seconds. Remember to enable roaming and mobile data to use it abroad.

What are the advantages of an eSIM for travel?

Quick to activate, no physical card, economical, and functional in over 200 destinations: the eSIM allows you to stay connected everywhere, without breaking the bank on roaming charges.

Does an eSIM work without Wi-Fi?

Yes. Once installed and activated, your eSIM connects you to the local mobile network. You do not need Wi-Fi to use your mobile data.

How to simplify your travels by eliminating roaming charges?
When abroad, your phone can quickly incur exorbitant charges, whether you monitor your usage or not. Indeed, most travelers have already faced phone bills well beyond their expectations. And who hasn’t heard of those unexpected and dreaded roaming fees?

Fortunately, there are several tips to reduce roaming costs while traveling. Whether you’re going for a long stay abroad or a weekend trip across the border to visit family, here are four essential strategies to avoid unexpected phone bills.

Four tips to reduce your roaming costs when traveling

When traveling abroad, several options are available to reduce roaming costs. There is no one-size-fits-all solution, but we’re revealing four effective strategies to consider. Each has specific advantages, so choose the one that best suits your next journey.

1. Consult your provider in advance

Before you leave, check with your provider about available options for international data. Some providers even offer free roaming. While these offers aren’t always included in the most economical plans, they can be very advantageous if you travel frequently.

Additionally, some providers offer free roaming data for certain countries or globally, even if the speed may be limited to 2G. If this meets your needs, this option is worth considering.

Finally, other providers offer temporary data packages. Rates may vary depending on the country, region, or duration of your stay. Don’t hesitate to ask many questions to find the solution best suited for your trip.

2. Rely on local Wi-Fi connectivity

Many travelers prefer to completely forgo mobile data and rely on available Wi-Fi hotspots in the area. This economical tip works very well in many urban areas but may be less effective in rural or isolated regions.

To do this, disable mobile data in your phone’s settings. Avoid relying on Airplane mode, as some background services might continue to use data. For added security, some prefer to remove their SIM card from their phone. Make sure you have a safe place to store it.

Without access to mobile data, your phone will only work on available Wi-Fi networks. Emergency services will remain accessible, and you can use GPS if you have downloaded local maps via Google Maps. Take advantage of this solution to facilitate your travels by:
- Looking for cafes offering free Wi-Fi.
- Accessing free Wi-Fi in public libraries or other municipal buildings.
- Considering a coworking subscription if you work as a freelancer.
- Being careful about unsecured Wi-Fi networks, especially open networks in unusual areas.
3. Opt for a local SIM card

Many seasoned travelers opt for local SIM cards during their stays abroad. Buy a SIM card directly on site and insert it into your phone to get a local number and access mobile data via local networks.

Used wisely, this solution proves to be both economical and practical for staying connected throughout your trip.

However, if this option seems too easy or too advantageous, it’s important to remain vigilant. While purchasing a local SIM card generally goes smoothly, some pitfalls can arise:
- The SIM card may not offer the promised services.
- Hidden fees may be applied.
- You might acquire a card incompatible with your device.
These risks are amplified in case of a language barrier or if you purchase from unauthorized resellers. It is therefore essential to gather information before making a purchase.

4. Switch to eSIM

Is your device compatible with eSIM technology? eSIM, or embedded SIM, is a tiny chip integrated directly into your phone. To activate it, you simply download a data plan from a provider or via an online platform. Once configured, you immediately benefit from mobile connectivity and data without having to handle a physical card.

The advantages of eSIM are numerous:
- Flexibility: Download multiple data plans and easily switch between them as needed during your travels.
- Savings: Access local plans at competitive rates thanks to partnerships between online platforms and providers.
- Dual SIM: Use your eSIM alongside your national SIM card without having to remove it. Simply deactivate your local SIM’s data while continuing to use calls and messages from your main number. Additionally, keeping your usual number facilitates authentications and other services requiring your personal number.
Save on roaming charges during your travels with Vostra

Roaming charges can quickly add up, but you don’t have to bear them on every trip. Apply these effective strategies to reduce your roaming costs while maintaining optimal connectivity during your stays abroad.

From Wi-Fi hotspots to adopting eSIMs, there are many ways to manage your connectivity while traveling. Don’t fall into the trap of expensive data plans and avoid spending your vacation stressing about the bill awaiting you upon your return. Instead, opt for one of these practical tips and fully enjoy your adventure worry-free.

SIM cards, eSIM: the best mobile solutions for sailors
Accessing reliable mobile coverage can be a challenge for sailors. Areas without terrestrial networks require specific solutions to stay connected. International SIM cards, local SIM cards, and eSIM – we help you choose the one best suited to your needs at sea.
Staying Connected at Sea: The Challenges

Connecting at sea is nothing like typical mobile use on land. Sailors face several obstacles, such as:
- No network coverage areas: Far from terrestrial antennas, phones cannot pick up a standard signal.
- Little to no Wi-Fi access: Ships are rarely equipped with reliable or high-performance Wi-Fi networks.
- High roaming charges: Even with limited coverage, roaming fees can quickly become prohibitive.
To overcome these challenges, it’s important to choose an adapted mobile solution that takes into account:
- The country being crossed: Some plans offer global coverage, while others are limited to a specific region.
- Data volume: Sailors often need a lot of data for video calls or internet browsing.
- Duration of the trip: A long journey requires a flexible, rechargeable, or adjustable solution.
Given these needs, several options stand out: international SIM cards, local SIM cards, and eSIM.

International SIM Cards for Sailors

International SIM cards, like « Travel SIM » offers, are designed to work in multiple countries or regions. They offer several advantages for sailors:
- Worldwide compatibility: They provide coverage in many countries without changing cards.
- Immediate use: Once the card is inserted, it’s ready to use without local configuration.
However, international SIM cards are not perfect:
- Included plans are often expensive, especially if you consume a lot of data.
- Recharge options at sea can be limited, as they require an internet connection.
- Physical cards can get lost or damaged.
In summary, international SIM cards are convenient, but they are not always suitable for intensive or long-term use.

Local SIM Cards: A Limited Solution

Local SIM cards are purchased directly in the country or region you are traveling in. With them:
- Costs are generally lower than international SIM cards.
- A local number facilitates national calls.
However, these cards have a few drawbacks if you work at sea:
- They only work in a given country. If you cross multiple borders, you will need to change cards.
- Recharges can be complicated at sea, as they require an internet connection.
- They are often designed for short-term stays, not for prolonged trips.
These limitations make local SIM cards poorly suited for sailors who need a flexible and international solution.

Why eSIM is Ideal for Sailors

An eSIM (embedded SIM) is a SIM card integrated directly into your device. Unlike physical cards, it offers the possibility to download a digital plan without physical manipulation. Its strengths 👇 :
- Worldwide coverage: eSIM plans offer coverage in over 200 countries.
- Quick activation: Download an eSIM plan online and activate it instantly.
- Convenience: No more need to change physical cards or visit a local store.
- Competitive costs: eSIM plans are often more affordable than physical alternatives.
However

Your phone must be compatible. Older models do not support this technology. Most recent smartphones, such as iPhones and recent Android devices, do have this feature.

Final Word

For sailors, choosing an adapted mobile solution is essential to stay connected at sea without interruption. While international and local SIM cards offer interesting options, eSIM stands out as the most flexible and practical solution. Prepare your trip now with eSIM offers on Vostra.world.

FAQ

What happens to my data if I delete my eSIM?
You’ve used an eSIM for a trip or business travel and are wondering what to do with it when you return? Deactivate or delete your eSIM. While these two actions seem similar, they have very different implications. In this guide, we explain when to choose one over the other, and how to do it step-by-step.
How to deactivate an eSIM

Deactivating an eSIM is an excellent solution if you want to keep your plan for future use. This method allows you to pause the line without deleting it, which is ideal if you are returning to the same region soon or if your plan is still valid.

Steps to deactivate an eSIM on your phone
- Go to your device’s settings.
- Go to the Mobile Data or Mobile Networks section, depending on your device.
- Select your active eSIM line.
- Tap the Deactivate this line option or an equivalent command.
Once deactivated, your eSIM remains installed on your phone, but it no longer uses data or network. This can be useful if you plan to reactivate this line on a future trip or to avoid accidentally consuming data.

Why deactivate instead of delete?

Choose to deactivate your eSIM if:
- You plan to reuse this plan on a future trip to the same region.
- Your plan is still valid, but you don’t need it immediately.
- You want to avoid having to download the eSIM card again.
Please note: deactivation does not extend the validity of your plan. If it expires while the line is deactivated, you will need to purchase a new plan or top it up, depending on the options offered by your provider.

When and why to delete an eSIM

Deleting an eSIM is a permanent action that erases the plan from your device. It also involves the loss of data associated with that plan. So, before you take the plunge, here’s what you need to know:

When is it necessary to delete an eSIM?
- The eSIM plan has expired and cannot be topped up.
- You no longer need this line and want to free up space on your device.
- You are changing regions or providers for a new eSIM plan.
In some cases, such as a lack of space on your device, deleting an inactive eSIM simplifies the management of your mobile networks.

What to keep in mind before deleting an eSIM

Using an eSIM: Impact on Battery Life and Energy-Saving Tips
With the growing popularity of eSIMs, some questions remain regarding their impact on mobile device battery life. One of the most frequent concerns is whether using an eSIM consumes more battery. In this article, we demystify this myth and provide practical tips to maximize your battery’s lifespan, especially when you’re traveling.

Using your eSIM in the right region

It is crucial to ensure that your eSIM plan matches the region you are in. For example, an eSIM designed for Europe will not work if you are traveling in North America or Asia.

This is due to differences in available phone networks and frequencies used in different geographical areas.

To avoid compatibility issues and ensure optimal use, here are some tips to apply 👇:
- Choose an eSIM plan suited to your destination when purchasing.
- Activate your eSIM before departing or upon arrival in the target region.
- Ensure your device is configured to automatically select compatible networks in the area you are traveling to.
By following these steps, you will avoid unnecessary interruptions and maximize your device’s energy efficiency, as a phone constantly trying to connect to an incompatible network can consume more power.

These tips extend your battery’s lifespan

When using an eSIM while traveling, it’s important to adopt certain habits that will help reduce your device’s energy consumption without compromising your user experience.
- Reduce your screen brightness: A very bright screen is one of the biggest power consumers.
- Activate airplane mode: When there’s no network or you don’t need a connection, this prevents constant signal searching.
- Limit automatic updates: These use data and consume battery, especially when roaming.
- Disable unnecessary services: Location, Bluetooth, or vibrations can be turned off when not needed.
- Use power-saving mode: This mode automatically adjusts several settings to extend your battery’s lifespan.
- Close unused apps: Some continue to consume resources in the background.
- Avoid heavy downloads: Large videos or files can quickly drain your battery.
- Use a portable charger: An external battery can be a practical solution, especially during long journeys or in poorly served areas.
These simple actions make a big difference in your device’s battery life, especially if you are on the go and using an eSIM to stay connected.

The real impact of eSIM on battery

Contrary to popular belief, eSIMs do not consume more battery than physical SIM cards. Here’s why:
- Integrated technology: eSIMs are directly integrated into the device’s hardware, eliminating the need for physical support. This reduces their impact on energy consumption.
- Optimized data management: eSIMs use modern protocols to transmit and receive data, making them more efficient than traditional SIM cards.
In summary, the eSIM does not represent an additional drain on your battery. However, other factors such as network coverage level or intensive use of certain applications can have a significant impact.

FAQ

Does an eSIM consume more battery than a physical SIM?

No, the eSIM is designed to be as efficient, if not more so, than a traditional SIM. It is integrated into the phone’s hardware and does not use more power than necessary to function.

What should I do if my battery drains quickly with an eSIM?

Make sure you have disabled unnecessary features (like location or excessive notifications) and are using power-saving mode. If you are on the go, a portable charger can also be useful.

What are the advantages of an eSIM for travel?

The eSIM offers increased flexibility to choose and activate plans tailored to your destination without changing a physical SIM card. It is also more convenient, as it prevents the loss or damage of a card.

Can I modify or change my eSIM plan?
Before using an eSIM, it’s essential to check two important things: is your phone unlocked by your current carrier, and is it compatible with eSIM technology? We’ll explain how to verify these essential aspects to take advantage of the many benefits of eSIMs.
How to check if your phone is unlocked?

To use an eSIM with a carrier of your choice, your phone must be unlocked (i.e., it must not be restricted to a single carrier). A locked device can restrict access to other networks, leading to additional costs or the inability to use foreign eSIMs. Here’s how to check if your device is unlocked:
- Go to Settings > Connections > SIM Manager.
- Look for the Carrier Lock section.
- If your device is unlocked, the message “No SIM restrictions” will appear.
How to check if your phone is compatible with eSIM technology?

eSIM compatibility is generally reserved for recent phone models (produced after 2018) that integrate eSIM technology.

For an iPhone:
- Go to Settings > Connections > SIM Manager.
- Scroll to Available SIM (iOS 15 or later versions).
- If the « Add eSIM » option appears, your device is compatible.
For an Android device:
- Dial *#06# and press Call.
- If an EID (eSIM Identifier) number appears, your device is eSIM compatible.
You can also check the official list of eSIM compatible phones on the Vostra website for confirmation.

Can I change my eSIM plan?

One of the great strengths of eSIMs lies in their flexibility. Unlike physical SIM cards, you can modify or change your eSIM plan according to your needs effortlessly. For example, you can:
- Increase the amount of available data if you run out.
- Change plans when traveling to a new destination.
- Adapt your eSIM to extend its validity for a longer-than-expected trip.
To modify your plan, log in to your Vostra account, select your eSIM, and choose the « Recharge » or « Change Plan » option.

Deactivating and deleting an eSIM

If you no longer need your eSIM, you can choose to temporarily deactivate it or remove it from your phone. This depends on your needs:
- If you plan to use this eSIM later, deactivate it to avoid permanent deletion.
- If the eSIM will no longer be useful, you can delete it from your settings.
Here’s how to deactivate or delete an eSIM:
1. Go to Settings > Cellular or Mobile.
2. Select the eSIM line to deactivate.
3. Tap Deactivate This Line.
You can reactivate this eSIM at any time if it remains registered on your device.

How to change your eSIM plan?

Here are situations where you might want to change your eSIM plan:

You’re running out of eSIM data

If you use your eSIM intensively and your plan is exhausted, easily recharge it via your Vostra account:
- Go to My eSIMs.
- Select the active eSIM.
- Choose the Recharge option and follow the instructions.
Your validity period expires

If your eSIM is about to expire, you can extend its validity by recharging or purchasing a new plan.
