Apple's mobile phone software always stops sending in the middle.

2. The mobile phone card is in arrears, and the mobile phone cannot enjoy the call and SMS service. Keep the balance of the mobile phone card sufficient before sending information.

3. The contact number edited when sending information is incorrect, which does not meet the standard of 1 1 digit mobile phone number.
