How to transfer a Firsty eSIM to a new phone
If you are switching to a new phone, your existing Firsty eSIM cannot be transferred directly to the new device. However, you can purchase a replacement eSIM through the Firsty app while continuing to use your existing Firsty account.
Can I move my existing eSIM to another phone?
No. Once an eSIM has been installed, its profile is permanently linked to the first device on which it was installed.
Unlike a physical SIM card, an eSIM cannot be removed and inserted into another phone. Its installation details cannot be reused on a different device.
Deleting the eSIM from your old phone does not unlock it or make it available for installation on your new phone.
Reinstalling on the same phone vs. switching phones
It is important to distinguish between reinstalling your eSIM on the same device and installing it on a different device.
Reinstalling on the same device
If you accidentally deleted your Firsty eSIM, you can reinstall it using the original QR code, provided that you are reinstalling it on the same phone.
Installing on a different device
If you are setting up Firsty on a new phone, the original eSIM and QR code will not work.
You must purchase a replacement eSIM because the original profile remains linked to your previous device.
How to get Firsty on your new phone
To purchase and install a replacement eSIM:
Download or open the Firsty app on your new phone.
Log in using your existing Firsty account.
Go to the Support section.
Select Purchase new eSIM.
Follow the instructions to purchase the replacement eSIM.
Complete the installation steps shown in the app.
A replacement eSIM costs a one-time fee of €0.90.
Replacement fee for partner customers
If you joined Firsty through an eligible partner, such as Belfius, Grab, or KBC, the €0.90 replacement-eSIM fee is waived.
Use the same process:
Support → Purchase new eSIM
You should not be charged during the replacement process. If the app asks you to pay or you need assistance, contact Firsty Support through the app.
Should I delete the eSIM from my old phone?
You do not need to delete your old eSIM before purchasing the replacement.
Deleting the eSIM does not make it transferable to your new phone. Consider keeping it installed until the replacement eSIM is working successfully on your new device.
After confirming that Firsty is working on the new phone, you can remove the old eSIM from your previous device if you no longer need it.
Need help?
If you cannot purchase or install your replacement eSIM, contact Firsty Support through the app.
Include your phone model, the error message shown, and whether you joined Firsty directly or through a partner.
