 Selecting Roaming Operator

Selecting Roaming operator

When you arrive at your overseas destination, most handsets will select a foreign network automatically after power-on. However, if your handset fails to do so, please refer to your handset user guide and follow the steps for manual network selection. The overseas network operator’s name will be displayed on your handset screen after successful selection and you are ready to make or receive calls.

If you cannot make calls for some reasons, please try to restart your handset and redial. The foreign network operator you selected may not support this roaming service, please select another operator manually and redial. The roaming destinations and roaming operators will be changed from time to time.
