Why failed to send a message to China Mobile?

Network problems, wrong number, account problems, etc.

1, network problems: unstable cell phone signal or network connection problems will lead to information transmission failure. You can try to move to an area with better network coverage or restart your phone to try to solve the problem.

2. Wrong number: confirm whether the sent mobile phone number is correct, including country code and area code.

3. Account number problem: there are arrears or other problems in the mobile phone account, which leads to the failure of information transmission. Ensure that the mobile phone account is normal and there is no arrears.
