Your eSIM will not be named “SimSIM” on your device — it appears under a local network’s name at your destination, which is normal. The eSIM you just installed always appears at the bottom of the line list. More details.
iOS 26 and later
1
Open My eSIMs in the app
In the SimSIM app, go to My eSIMs and open the plan you purchased. A plan that hasn’t been installed yet is marked as ready to install. If you bought several plans, make sure you pick the one for your current destination.
2
Tap the install button
Tap Install eSIM. The app passes the profile straight to iOS — there’s no QR code to scan and no codes to enter manually.
3
Approve adding the eSIM
Your iPhone will ask permission to add a new eSIM. Approve it and wait for installation to finish. This takes a few minutes, and you can keep using your phone meanwhile.
4
Choose "Data Only"
When asked what the line is for, choose Data Only. The new line then handles internet only, while your calls and messages continue through your regular number.
5
Finish the installation
Tap Done. The eSIM is now installed on your device.
6
Turn on the new line
Select the newly configured eSIM and turn the line on. Until you do, the line exists on the device but is inactive.
7
Confirm data roaming is enabled
Go back to the previous screen, tap the eSIM you just enabled, and confirm Data Roaming is on. This is the step most people miss — without it the eSIM is installed but you’ll have no internet at your destination.
8
After you land — switch your data line
Once you arrive, go to Settings → Cellular → Cellular Data and select the eSIM you set up. From this point your browsing runs through the plan you purchased.
