Why eSIM Transfer Matters for Travelers
An eSIM is convenient because there's no physical SIM card to lose.
But that convenience creates a common misconception:
“If I can transfer everything else to my new phone, surely I can transfer my eSIM too.”
Not necessarily.
Modern iPhones and some Android devices support built-in eSIM transfer features. Apple, for example, supports eSIM Quick Transfer for carriers that participate in the feature. With iOS 26, Apple also supports some eSIM transfers between Android and iPhone when the carrier and devices are compatible.
However, the phone's transfer capability does not automatically mean a travel eSIM provider supports transfer.
Can You Transfer a SIMZY eSIM to a New Phone?
Yes, but it's not an automatic phone-to-phone transfer.
SIMZY's current terms provide a specific process for customers who need to move an eSIM to a new device.
You need to:
- Keep your existing SIMZY eSIM on the old device if possible.
- Contact SIMZY Customer Services.
- Request a new QR code for the new device.
- Install the new eSIM on your replacement phone.
- Confirm that the new phone connects successfully.
- Follow SIMZY's instructions regarding the old eSIM.
Can You Transfer an Airalo eSIM to a New Phone?
No. Airalo's official help center is very clear on this point.
Once an Airalo eSIM has been installed, it is tied to that device and cannot be transferred to another device.
What Happens If You Still Have Data Left?
This is probably the biggest issue.
Imagine you're on day 10 of a 20-day holiday.
You've got: 8 GB remaining.
Then you replace your phone.
With SIMZY
You have a support route: contact SIMZY Customer Services and request a new QR code for the new device.
Because your specific plan and situation can affect how the service is handled, contact SIMZY before deleting the old eSIM.
With Airalo
The remaining data cannot be transferred to the new device according to Airalo's current help documentation.
If the old phone still works, Airalo suggests continuing to use the data there or sharing it with the new device through a personal hotspot.
What If You're Switching From Android to iPhone?
The situation is similar.
Apple now supports some Android-to-iPhone eSIM transfers with iOS 26, but only with supported carriers and compatible devices. Apple says that where the carrier or device doesn't support the feature, you may need carrier activation or a QR code.
That means a travel eSIM purchased from a third-party provider still needs to support the relevant process.
For SIMZY:
Contact Customer Services and request a new QR code.
For Airalo:
The installed eSIM cannot be transferred to another device.
Setup and App Experience: Don't Let the Transfer Issue Surprise You
The best time to think about eSIM transfer isn't when your phone has already broken.
It's before your trip.
When installing a travel eSIM, keep a record of:
- Your purchase confirmation
- Your eSIM details
- Your provider account
- Customer support information
- Your plan validity
- Your remaining data
- Your activation instructions
This is particularly important if you're traveling internationally.
If your phone stops working, you may need another device to access your email or support account.
A Better Way to Upgrade Your Phone Before Traveling
If you know you're getting a new phone before your trip, the solution is simple.
Don't install the eSIM on your old phone.
Instead:
Buy the eSIM → get your new phone → install the eSIM on the new phone → test it → travel.
SIMZY provides installation instructions and recommends having a stable internet connection during the eSIM installation/activation process.
Airalo similarly recommends installing the eSIM before travel when you have a reliable internet connection.
