The following troubleshooting advice is intended as a general guide only. The features and menus on your device may be different so you will need to refer to your device’s user guide and if necessary, contact the manufacturer direct.
If your device is not registering with any networks (device shows no signal strength, or a “No service”, “Emergency Calls Only”, or similar message):
1) Check that your device is not set to ‘Airplane Mode’.
Settings > Airplane Mode
2) Check that your ‘Network Mode’ is set to use both GSM(2G) and WCDMA(3G) networks.
Settings > Cellular > Enable 3G
3) Check that your ‘Network Selection Mode’ is set to ‘Automatic’.
iPhone/iPad:
Settings > Carrier > Automatic = ON
4) After all these checks, re-start the device for the changes to take effect.
5) If you have tried the above steps, but are still having problems, try a manual network selection.
Settings > Carrier > Automatic = OFF > Select a network once listed
