How to make a call on a Dual SIM iPhone

With the Dual SIM feature of smartphones, you can simultaneously use an eSIM and a physical SIM card. This configuration allows you, for example, to use the eSIM’s mobile data to access the Internet, while keeping the physical SIM card for making and receiving calls.

- Have an unlocked phone or have plans from the same carrier.
How to proceed?
1. Open Settings > Cellular Data (or Mobile Data) and choose the line you want to set as default for calls and messages not in your directory.
2. Each time you wish to switch from one of your lines to the other, go back to Settings > Cellular Data/Mobile Data and activate the desired line by selecting Turn On This Line.
You can thus switch between your different lines at will, with ease and fully enjoying the benefits of Dual SIM on your iPhone.

eSIM: The guide to understanding and making better use of this technology
For years, staying connected abroad has been a real headache: between buying a local SIM card and the exorbitant roaming fees imposed by operators, it was difficult to find a satisfactory solution… until now. eSIMs, already on the market for several years, are finally getting all the attention they deserve.

Wondering how these famous eSIMs work? Good news: you’ve come to the right place! Discover everything you need to know about this small technological revolution, capable of simplifying your travels and allowing you to stay connected wherever you are.

What are eSIMs and why are they important?

Almost all phones need a SIM card to access the mobile network and make calls. Usually, you have to slide this small plastic chip into a tray (or even remove the back cover if you have an older model). You know the routine: it quickly becomes tedious when you’re juggling multiple phones or SIM cards.

Fortunately, the eSIM changes the game. Integrated directly into the smartphone’s motherboard, this tiny chip does everything a physical SIM card does… without any manipulation. Today, many modern devices already offer eSIM in addition to the usual SIM tray.

eSIMs offer real advantages compared to traditional SIM cards.
- Firstly, you can store multiple data plans simultaneously, without being limited to a single subscription.
- Their ultra-compact format frees up space in your smartphone, allowing manufacturers to strengthen other essential components… like the battery!
- You no longer have to handle hardware parts: no more laborious disassembly or searching for a paperclip to eject a tray!
Learn more about how eSIMs work, the digital equivalent of a traditional SIM card

We are often asked if the eSIM works exactly like a physical SIM… and the answer is simple: YES!

All eSIM-compatible smartphones offer an option in their settings to add a cellular plan (here are the instructions dedicated to iPhones).

On the Vostra platform, activating a data plan takes only a few seconds: you can install the eSIM by scanning a QR code, manually entering the information, or directly via the app. You then immediately have a volume of mobile data valid for the duration of your choice.

Key takeaway:

With this data plan completely independent of your usual operator, say goodbye to exorbitant international fees! And don’t worry, you’ll still keep your phone number, of course. The Vostra eSIM instantly connects you to local networks in over 200 countries, providing you with ultra-fast data access like never before.

With Vostra, renew or change your eSIM data plan anytime and set up a new one in less than five minutes. No contract is required!

Is the Dual SIM function identical to the eSIM function?

Not necessarily!

The term « Dual SIM » simply means that a smartphone can accommodate multiple SIM cards. However, this doesn’t necessarily mean that one of these cards is an eSIM. In reality, many « Dual SIM » phones offer two physical SIM card slots, clearly visible on their dedicated tray.

Conversely, some more advanced models allow for combining a SIM card and an eSIM, or even using two eSIMs together, while still retaining the « Dual SIM » designation.

Where can (and can’t) you use an eSIM?

eSIM data plans covering over 200 countries and regions are available on the Vostra platform! This technology is already adopted by most major European operators, as well as in international hubs such as Canada, Hong Kong, India, Qatar, Singapore, Taiwan, and the United States. In other words, wherever you go, you are very likely to find a suitable eSIM plan.

Prefer to stay with your current operator? Most also offer an eSIM option, which simply replaces your physical SIM card. However, depending on the case, you may need to contact customer service or visit a store, which can slightly extend the waiting time.

Adventure has no limits, and thanks to Vostra, neither does your mobile data

You now know more about how eSIMs work, these digitized SIM cards integrated directly into your phone. They are impossible to lose, and you can store several at once. The result: you enjoy almost immediate access to local plans anywhere in the world.

Dual SIM: how to use eSIM and SIM card at the same time?
The eSIM is a game-changer for connected travelers. No more juggling traditional SIM cards upon arrival at your destination: everything is done remotely, directly from your smartphone. Discover the real differences between physical SIM cards and eSIMs, and how to use both technologies simultaneously when traveling abroad.
Differences between physical SIM card and eSIM

Unlike traditional SIM cards, eSIMs are digital SIM cards directly integrated into the device. This allows for faster and more secure setup.

You can install an eSIM without going through a point of sale or waiting for postal delivery. Since the eSIM is embedded in the phone, it cannot be removed or stolen.

No physical manipulation means fewer technical problems related to wear and tear or poor contacts. eSIMs are more eco-friendly, and therefore more sustainable, as they avoid plastic production and unnecessary shipping.

Using a SIM card and an eSIM simultaneously: how-to guide

If your smartphone is Dual SIM compatible, you can use both a physical SIM card and an eSIM. This can be practical for separating professional and personal use, or for activating a local line during a trip while keeping your main line active.

1. Label your plans

To avoid confusion, assign a name to each line (e.g., “SIM France” and “eSIM Thailand”).

On iOS:
- Open Settings > Cellular.
- Tap on your eSIM, enter a custom name, then save.
On Android:
- Go to Settings > Network & internet > SIM cards.
- Select your eSIM and name it.
2. Activate your eSIM

On iOS:
- Open Settings > Cellular.
- Select your eSIM.
- Activate Turn On This Line and Data Roaming.
- Choose a supported network if necessary.
On Android:
- Go to Settings > Network & internet > Mobile network.
- Activate the eSIM, Mobile data, and Roaming.
3. Set your default lines

Voice calls:

Choose which card to use for outgoing calls and SMS.
- iOS: Settings > Cellular > Default Voice Line.
- Android: Settings > Network > SIM card > Calls/SMS.
Mobile data:

Choose the line to use for internet access.
- iOS: Settings > Mobile data > select eSIM.
- Android: Settings > Mobile network > select eSIM.
Switching from an eSIM to a physical SIM card (or vice versa)

You can temporarily deactivate your eSIM at any time, for example after a trip, and reactivate your usual SIM card for calls and data. This avoids having to reinstall an eSIM profile later.

Deactivate an eSIM
- iOS: Settings > Mobile Data > eSIM > deactivate.
- Android: Settings > Connections > Mobile network > deactivate eSIM.
Is your phone compatible with eSIMs?

Most recent smartphones (since 2018) are compatible with eSIM technology. However, your device must also be unlocked (not tied to a specific carrier).

To check, consult the official list of compatible models or dial *#06# on your device to see if it displays an EID (eSIM identifier) number.

Dual SIM smartphones also allow you to combine an eSIM and a physical SIM in parallel. This is ideal for travelers who want a local line while keeping their main number active.

FAQ

Can I use my main SIM card for calls while using an eSIM for internet?

Yes, this is entirely possible if your phone supports dual SIM. You can configure your eSIM to handle mobile data (internet), while keeping your physical SIM card for calls and SMS. Simply set the default lines in your phone’s network settings.

How many eSIM profiles can I save on a single phone?

Most modern smartphones allow you to save between 5 and 8 eSIM profiles. However, only one can be active at a time. This allows you to keep multiple international plans and activate them depending on the country you are in.

What happens if I change phones? Will my eSIM still work?

The eSIM is linked to a single device. If you change phones, you will generally need to download a new eSIM profile via your carrier or a platform like Vostra. This is quick, but it requires a new activation.

How do I prioritize one line for calls, and another for internet?

In your phone’s settings, you can choose which line to use for mobile data, for voice calls, and for SMS. These options are found in the « Mobile network » or « Cellular data » section. You can change these settings at any time.

How do I delete an eSIM that I no longer use?

You can delete an eSIM profile in your phone’s settings, in the « Mobile Data » or « Mobile Network » section. Please note that deletion is permanent: if you wish to use it again, you will need to request a new QR code or reactivation via your provider.

- eSIM: Integrated into the device and remotely programmable, eliminating the need for physical cards.
eSIMs make it possible to store several operator profiles on the same device, providing a fluid transition between different networks.

Will an eSIM work on my device?

To use an eSIM, your smartphone must be:
- eSIM compatible: Most recent models (iPhone, Samsung, Google Pixel, etc.) support this technology.
- Unlocked: An unlocked phone is not restricted to a single operator and can use an eSIM from any provider.

Some countries require electronic identity verification (eKYC) before authorizing the activation of an eSIM plan. This involves providing identity documents to validate your account. If your destination imposes this requirement, remember to complete this verification before your departure.

Recharge option

Many eSIM plans allow you to recharge your data without having to reinstall the eSIM. If your plan does not offer this option, you will need to purchase a new one upon expiration.

Frequently Asked Questions

How does a Vostra eSIM work?

A Vostra eSIM allows you to connect to a mobile network without the need for a physical SIM card. Once activated, it gives you access to mobile services such as data, calls, and SMS (if included in the plan). The eSIM operates entirely digitally, unlike a traditional SIM card, which makes it easier to activate and use, especially for travelers.

When is the best time to install an eSIM?

The ideal time to install your eSIM depends on its activation policy. If your eSIM activates immediately after installation, it’s best to wait until you are ready to use it before installing it on your device. However, if it only activates upon connecting to the network at your destination, you can install it any time before your departure.
When and how to activate an eSIM?
eSIMs have different activation policies, depending on the operator and the type of plan chosen:

Immediate activation: Some eSIMs are activated as soon as they are installed on your device. They then start consuming their plan immediately.

Activation upon connection: Other eSIMs only activate when they detect a mobile network in the area covered by the plan.

Make sure to check your eSIM’s activation policy before installing it.
Can I use an eSIM with a locked phone?

No, your phone must be unlocked by your operator to use an eSIM. An unlocked phone means you are not tied to a single operator and have the freedom to change plans, use an eSIM, or a local SIM when you travel. If your device is locked, contact your operator to see if it can be unlocked.

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.

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.

From Wi-Fi hotspots to adopting eSIMs, there are many ways to manage your connectivity while traveling.
