How to Restart iPhone After Unlocking SIM Card with EasySimUnlocker

Unlocking your iPhone’s SIM card allows you to switch carriers and use your phone freely. However, after unlocking, restarting your device is often necessary to ensure proper activation and avoid network issues. In this guide, we’ll explain why restarting is important, provide step-by-step instructions, troubleshoot common problems, and show how EasySimUnlocker offers a secure and permanent unlocking solution.

Why Restarting Your iPhone is Necessary After Unlocking the SIM

When you unlock your iPhone’s SIM, your device needs to refresh its network settings to detect the new carrier. Restarting helps with:

Network Refresh – Ensures the phone properly connects to the new network.
Avoiding Errors – Prevents issues like “Invalid SIM,” “No Service,” or “SIM Not Supported.”
Carrier Profile Update – Some network changes only take effect after a restart.
Ensuring Full Unlock Activation – Restarting completes the unlocking process.

Skipping this step can lead to connection problems or prevent your iPhone from recognizing the new SIM.

Step-by-Step Guide to Restarting an iPhone After SIM Unlock

Restarting your iPhone depends on the model. Follow the steps below for your specific device:

For iPhone 15, 14, 13, 12, 11, X Series

Press and hold the Side button and either Volume button until the power-off slider appears.
Drag the slider to turn off the iPhone.
Wait for 30 seconds to allow the system to reset.

What to Do if Your iPhone Doesn’t Recognize the Unlocked SIM

After unlocking and restarting, your iPhone should detect the new SIM. If it doesn’t, try these troubleshooting steps:

1. Remove and Reinsert the SIM Card

Use a SIM ejector tool or a paperclip to remove the SIM tray.
Take out the SIM card and check for dust or scratches.
Reinsert the SIM properly and restart the phone.

2. Enable and Disable Airplane Mode

Open Settings > Airplane Mode and turn it ON.
Wait 10-15 seconds, then turn it OFF.
This forces your iPhone to reconnect to the network.

3. Check for Carrier Settings Update

Connect to Wi-Fi.
Go to Settings > General > About.
If an update is available, you’ll get a prompt to install it.

4. Reset Network Settings

Open Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
Enter your passcode and confirm.
This will reset Wi-Fi, cellular, and Bluetooth settings (but won’t delete your data).

5. Try a Different SIM Card

If your iPhone still doesn’t detect the SIM, try inserting another carrier’s SIM.
If another SIM works, the issue may be with your carrier.
