How to Fix iPhone Activation Errors After an iOS Update (2026)
After a major iOS update, some iPhones get stuck on the activation screen. Here's how to fix it.
Fix 1: Try a different network
Switch between Wi-Fi and mobile data, or try a different Wi-Fi network. Activation requires internet.
Fix 2: Activate via Finder or iTunes
- Connect your iPhone to a Mac (Finder) or PC (iTunes) with a USB cable.
- Select your device and follow the prompts to activate.
Fix 3: Remove and reinsert SIM
Use a SIM ejector tool, wait 10 seconds, reinsert. Often resolves cellular activation failures.
Fix 4: Remove device from Apple ID
- On another device, go to appleid.apple.com.
- Under Devices, find your stuck iPhone → Remove from Account.
- Try activation again.
Fix 5: Recovery Mode restore (last resort)
- iPhone 8+: Press/release Vol Up → press/release Vol Down → hold Side button until recovery appears.
- iPhone 7: Hold Vol Down + Side button.
- iPhone 6s and earlier: Hold Home + Top button.
In Finder or iTunes, click Restore. This erases the device.
