What to Do When Your Phone Shows No Service or SOS

If your phone displays SOS, No Service, or cannot connect to the network, please follow the steps below.

Step 1. Restart Your Phone

Turn your phone off and wait 30 seconds before turning it back on.

If you are using a physical SIM card, please remove it, reinsert it, and then power the device back on. 

Most issues can be resolved by simply restarting your device.

Once you restart your device, try making a call. If you still have the same trouble, move on to the next step.

Step 2. Reset your network Setting 

This will only refresh your device’s network connections, including WiFi, mobile data, and Bluetooth.

• iPhone : Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
• Android : Settings > General Management or System > Backup and Reset or Reset Options > Reset Network Settings

Step 3. Check your VPN settings

Some VPN services may interfere with your mobile network connection.

If a VPN is active, disconnect it or delete the VPN configuration, then try reconnecting to the network again.

Step 4. If the Issue Still Isn’t Resolved

If none of the steps above resolve the issue, please contact the PhoneBox Customer Support team
