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
- eSIM plans are limited to a validity period. If you delete an expired eSIM, you will not be able to reactivate it.
- You cannot transfer a deleted eSIM to another device, even if it is still valid.
- Deletion is irreversible: you will need to purchase a new plan if you need it again.
What happens if I delete my eSIM?

Deleting an eSIM can have significant consequences, especially if it is still valid or if you are traveling. Here’s what it entails:
- You will lose access to your plan, even if it is still active.
- You will need to purchase a new eSIM plan to restore your connectivity.
- You could be without a connection if you don’t have an alternative solution (Wi-Fi or physical SIM card).
Steps to delete an eSIM
- Open your phone’s settings.
- Go to the Mobile Data section.
- Select the eSIM line you wish to delete.
- Click the Delete this plan option and confirm your choice.
Before deleting an eSIM, make sure you have backed up all important information or have a backup plan to stay connected.

For reliable and easily rechargeable eSIM plans, explore the offers available on Vostra.world and stay connected wherever you are.

FAQ

Can I reactivate an eSIM after deleting it?

No, a deleted eSIM cannot be reactivated. You will need to purchase a new plan or contact your operator to get another one.

Does deleting an eSIM free up space on my phone?

Yes, deleting an eSIM can free up a small amount of space on your device, especially if you manage multiple plans.

How do I check if my eSIM plan is still valid?

You can check the validity of your plan in your phone’s settings or via your provider’s app. On Vostra, log in to your account to check your balance and validity period.

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 does an eSIM recharge work?

Imagine you’re traveling to London and using an eSIM with a 3 GB plan valid for one week. After using your data to browse social media, look for places to visit, and share memories, you notice your usage reaches 90% of your plan. Don’t panic! A recharge is enough to extend your connectivity.

This way, you get fast and convenient mobile connectivity, wherever you are in the world.

eSIM plans vary based on several criteria:
- The volume of data included.
- The validity period (for example, 7 days or 30 days).

1. Log in to the Vostra app.

Using your iPhone abroad: tips and advice to avoid unpleasant surprises
Before setting off on your next great adventure, take the time to properly prepare your iPhone. A few simple settings will allow you to travel with peace of mind, ensuring your security, connectivity, and tranquility. International journeys can hold their share of surprises, so it’s better to anticipate. Discover below the essential steps to follow before your departure to avoid any issues once you’re there.

6 things to do with your iPhone before going abroad

You’re about to pack your bags for an international getaway, and your iPhone is naturally part of the trip. But before you go through customs, take a few minutes to prepare your precious high-tech companion: here are our six essential tips to fully enjoy your iPhone abroad.

1. Make sure your iPhone is unlocked

A locked phone can become a real headache abroad, preventing you from using local SIM cards or even eSIM plans. If your iPhone is locked by your carrier, contact them without delay to have it unlocked.

Generally, stating that you are going abroad and wish to have a local number is sufficient. And if your carrier doesn’t cooperate, other solutions exist, which you can turn to.

2. Turn off data roaming before takeoff

To avoid unpleasant surprises, disable data roaming before leaving national territory. Better yet, completely turn off mobile data during your trip, at least during transit, to prevent any unwanted connection to a foreign network.
- Go to Settings
- Tap Mobile Data
- Open Data Roaming and turn it off
- Go back to Mobile Data and turn it off as well
3. Use Wi-Fi services to your advantage

Wi-Fi can be your best ally for saving your mobile data and avoiding hefty bills.
- Native Apple Apps: iMessage, FaceTime… Your integrated tools already facilitate calls and messages via Wi-Fi.
- Facebook Messenger: No need for an active Facebook account to chat freely.
- WhatsApp, Telegram, Line: Perfect for calling and sending secure messages across the world.
  Even if you opt for a local SIM card or an eSIM plan, Wi-Fi remains the ideal solution for reducing your data consumption.
4. Choose an eSIM plan tailored to your needs

Simplify your connection with an eSIM plan that offers you access to local data at advantageous rates, directly from your smartphone. Purchase your plan in advance and activate it effortlessly upon arrival.

Although you won’t have a local number (requiring Dual SIM functionality or a messaging/calling app), your phone will remain fully operational, thus avoiding costly roaming charges.

5. Update your Multi-Factor Authentication (MFA)

Protect your accounts with robust multi-factor authentication. Most 2FA methods rely on SMS, which can be problematic abroad if you don’t have phone service. Avoid being locked out by updating your security options before you leave.

A few tips:
- Add a backup email address.
- Use a Google Voice number or temporarily forward your number to Google.
- Opt for an app-based authenticator like Google Authenticator or LastPass Authenticator.
6. Monitor and reset your data usage

Keep control of your data usage while traveling, as measurement methods can vary from country to country. Quickly identify data-hungry apps and adjust your settings to avoid overages.

To reset your data usage statistics on an iPhone:
1. Go to « Settings »
2. Select « Mobile Data »
3. Tap « Reset Statistics »
This way, you will have a clear view of your data consumption throughout your stay.

Get ready to travel stress-free

Just as you meticulously plan your itinerary and budget, also prepare your iPhone for a successful trip. Make sure you can use local SIM cards or eSIM plans, and update your security settings.

Leave nothing to chance:
- Stay connected with a suitable plan thanks to a Vostra eSIM, simple and quick to obtain.
- Save time, money, and stress by preparing your phone before you leave.

eSIM Card: The guide to understand and better use 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, which have been on the market for several years, are finally attracting 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 drill: it quickly becomes tedious when 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 over classic SIM cards.
- Firstly, you can store several data plans concurrently, without being limited to a single subscription.
- Their ultra-compact format frees up space in your smartphone, allowing manufacturers to reinforce other essential components… like the battery!
- You no longer have to handle hardware parts: no more laborious disassemblies or hunting 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 an 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. Then, you immediately have a volume of mobile data valid for the duration of your choice.

What you need to remember:

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

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

Is Dual SIM functionality the same as eSIM functionality?

Not necessarily!

The term “Dual SIM” simply means that a smartphone can accommodate multiple SIM cards. However, this does not mean that one of these cards is necessarily 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 you to combine a physical SIM and an eSIM, or even use 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 has already been 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 set foot, you are very likely to find a suitable eSIM plan.

Do you prefer to stick with your current operator? Most also offer an eSIM option, which simply replaces your physical SIM card. Nevertheless, depending on the case, you may need to contact customer service or visit a store, which can 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. It’s impossible to lose them, and you can store several at once. The result: you enjoy almost immediate access to local plans worldwide.

This is the ideal solution for frequent travelers, and it’s rapidly becoming widespread. Ready to take the plunge? Explore Vostra’s eSIM plans now!
