I am in Korea, and my mobile phone is in arrears some time ago. After recharging the next day, the mobile phone can't answer calls and text messages, showing no service.

General number arrears will not automatically turn off the international roaming function. If this function cannot be used, there may be the following reasons:

1. Some countries or regions have different network standards and frequency bands, so it is necessary to replace appropriate mobile terminals to use the international roaming function;

2. The mobile phone is set to automatically select the network, and no operator can be found to cooperate with our company. You can manually select a network by changing the setting to "Select Network Manually".

If the above problems still cannot be solved, you can call the international, Hong Kong, Macao and Taiwan roaming customer service hotline+8618610010 for free service feedback (free only when you call with our mobile phone).

In addition, you can log in to the online business hall /v to participate in activities!
