eSIM not working: reasons and solutions to all typical problems

📱 What is eSIM and why you need it

eSIM — an embedded SIM card that is activated via QR code or operator app. No need to insert a physical card. Convenient for travel, a second number, and quick operator switching.

🔧 10 reasons and solutions

1. Device does not support eSIM. Check the model on the manufacturer's website. eSIM is available on iPhone XS and newer, Samsung Galaxy S20+, Pixel 3+.
2. QR code will not scan. Clean the camera, increase the brightness of the screen with the code, try entering the data manually.
3. eSIM will not activate. Make sure Wi-Fi is turned on — activation requires internet.
4. No network after activation. Restart your phone. Go to Settings → Cellular → select your eSIM.
5. Roaming does not work. Enable data roaming in cellular settings manually.
6. Profile already used. QR code is one-time use. Contact your operator for a new one.
7. eSIM limit reached. iPhone stores up to 8 eSIMs, but only one can be active. Delete unused ones.
8. Incorrect APN. Clarify the APN with your operator and enter it manually in settings.
9. Phone is locked to an operator. Unlock your device with your operator before installing another eSIM.
10. Error downloading profile. Turn off VPN and try again.

❌ Common user mistakes

• Scanning QR code without Wi-Fi connection
• Attempting to use one QR code twice
• Not switching to the correct eSIM in settings
• Forgetting to enable data transfer for the new eSIM
