Why can't my family abroad successfully send me a mobile message?

If your family has started international roaming, but can't send short messages abroad, you can remove the obstacles by the following methods:

1. Please check whether the SMS settings are correct.

2. When sending short messages to international, Hong Kong, Macao and Taiwan users, the sending format is "00+ opposite country code+opposite number" or "+opposite country code+opposite number".

3. In some countries and regions, the network only supports "00" transmission mode.

If you need help, please call the global toll-free service hotline+8618618610010 (only when roaming abroad, it is free to call with Unicom's mobile phone number).
