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

1. Connect your iPhone to a Mac (Finder) or PC (iTunes) with a USB cable.
2. 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

1. On another device, go to appleid.apple.com.
2. Under Devices, find your stuck iPhone → Remove from Account.
3. 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.
