"I want to move my eSIM to my new phone." "I accidentally scanned the QR code on a family member's device." When it comes to eSIMs, plenty of travelers run into trouble trying to "move" or reinstall them. Prepaid travel eSIMs in particular can cause unexpected headaches if you don't understand how they work.
- Travel eSIMs usually can't be reinstalled on a different device once set up
- Always install the eSIM on the device you'll actually use
- Don't delete the eSIM until you're finished with it (deleting may make it unusable)
- Once it's installed, you may not be able to move it — even before you've used any data
- It's a data-only eSIM (no phone number, SMS, or voice calls), but app-based calls such as WhatsApp work over data
Here's the bottom line: with travel and prepaid eSIMs, once you install the profile, in most cases you can't reinstall it on a different device. That's why it's important to install it on the device you actually plan to use, and to avoid deleting the eSIM until you're done. In this article, we'll walk through why this happens, what to watch for in different situations, and how to avoid common mistakes — in plain terms, even if it's your first eSIM.
What does "reinstalling an eSIM" actually mean?
Reinstalling an eSIM means taking a profile you've already set up on one device and adding it again to a different device. Many people picture it like a physical SIM card you can pop out and swap between phones — but an eSIM is written into the device itself, so in many cases it can't be moved the same way. With travel, budget, and short-term data eSIMs especially, it's safest to plan as if reinstalling isn't possible.
Why can't you just move it to another device?
The main reason is that, as a rule, each eSIM can usually be installed only once (this applies whether you use a QR code or manual setup). The moment you install it on the first device, the eSIM is treated as "used," and if you try to set it up on another device you'll likely see something like:
- "This code has already been used"
- "Unable to add eSIM"
- "Activation failed"
In other words, if you scan the same QR on an Android phone or a second iPhone after installing it on the first one, it often won't be accepted.
Situations where you need to be careful
1. You upgraded or switched to a new phone
If you buy a new phone after purchasing your eSIM, in most cases you can't simply move the eSIM from the old device to the new one. If you're planning to change phones, it's safest to set it up on the new device you'll actually use.
2. You accidentally scanned it on someone else's device
This is the "I'll just scan it on whatever phone is handy" situation — and the result is that you can no longer set it up on the device you really wanted to use. Before scanning, always confirm whether that device is the one you'll actually travel with.
3. You deleted it and tried to reinstall
It's easy to assume "if I delete it, I can just add it again," but with travel eSIMs, deleting does not necessarily mean you can re-issue it. Deleting can make the eSIM unusable, so this calls for extra caution.
Be especially careful with "delete"
This is the single most important point. Deleting an eSIM in your Settings app is easy to do — but with travel eSIMs, deleting it may be irreversible. Even if your reason is just "I want to tidy up" or "clear out old profiles," we recommend you don't delete it until you're finished using it.
You may not be able to move it even before you start using data
Even if you "haven't arrived yet," "haven't used any data," or "haven't activated it," once the profile has been installed, reinstalling it on a different device may no longer be possible. Don't assume it's safe just because you haven't started using data yet.
There are exceptions (some carriers and providers)
Some carrier-based eSIMs and certain providers do support "eSIM re-issue," "device transfer," or "QR code re-issue." That said, with travel eSIMs, budget eSIMs, and short-term data eSIMs, it's safest to plan on the assumption that reinstalling isn't possible. Since support varies by service and plan, please check the latest terms before you buy.
A checklist to avoid mistakes
| When | What to do |
|---|---|
| Before buying / setting up | Decide which device you'll actually use on your trip |
| When scanning the QR code | Confirm it's really the device you'll use before scanning |
| After setup, while in use | Don't delete the eSIM until you're finished |
| If you plan to change phones | Set it up on the new device / check the terms before buying |
If you're using Bloomy eSIM
The same basic principles apply to Bloomy eSIM. Please keep these points in mind:
- An eSIM is designed to be used on the first device you install it on. In most cases it can't be reinstalled on another phone, so be sure to set it up on the phone you'll actually use.
- After installing, don't delete the eSIM until you're finished using it.
Note that Bloomy eSIM is data-only: it does not include a phone number, SMS, or voice calls, though app-based calls (such as WhatsApp) work over your data connection. Usage is subject to a fair use policy, and connection quality can vary depending on the local network, your device, and your location. If you need a phone number or SMS, please also look into a separate option. Before setting up, it's a good idea to confirm that your device supports eSIM. Pricing, supported countries, and plan details may change, so please confirm them at the time of purchase.
Frequently asked questions
- Can I move an eSIM to another device?
- With travel and prepaid eSIMs, in most cases you can't reinstall the profile on a different device. Choose the device you set it up on carefully.
- If I delete an eSIM, can I use it again on another device?
- Deleting it doesn't guarantee you can re-issue or reuse it. Deleting can make it unusable, so we recommend not deleting it until you're finished.
- Can I move it if I haven't used any data yet?
- Even before you start using data, once the profile is installed you may not be able to reinstall it.
- What should I do if I'm changing phones?
- It's safest to set it up on the new device you'll actually use. Check the terms before buying for how any remaining period and data are handled.
In summary
Travel eSIMs often can't be reinstalled on another device once set up, and deleting one can leave it unusable. There's no need to overthink it — there are really just two things to remember: "set it up on the device you'll actually use" and "don't delete it until you're finished." Keep these two in mind and you'll avoid almost all of the trouble around moving and reinstalling.
