Troubleshooting common iPhone 15 issues
QR code won't scan
If your iPhone 15 camera doesn't recognize the QR code, try these solutions: clean the camera lens, ensure good lighting, and adjust the distance between the phone and the code. If the problem persists, you can manually enter the code by selecting the manual activation option in Settings.
eSIM option not appearing in Settings
If you don't see the option to add an eSIM, your iPhone 15 may be carrier-locked. Check with your current carrier if the device is unlocked or visit our page eSIM for travel for more information.
eSIM not activating after installation
If the eSIM appears installed but does not activate, restart your iPhone 15 and go back to Settings > Cellular to activate it manually. If the problem persists, contact PuraSim support.
Weak signal or no data with eSIM
Ensure the PuraSim eSIM is set as the default line for cellular data. Go to Settings > Cellular > Default Data Plan and select the PuraSim line.
