How to deal with the failure of sending international SMS by mobile phone;

1. Check whether the mobile phone is in arrears;

2. Check whether the method of sending international short messages is correct. The correct sending method is 00+ country/region code+user number;

3. Check whether it is normal to send text messages to other mobile phone numbers;
