Why do mobile phones receive garbled text messages?

The possible reasons why mobile phones receive garbled short messages are: 1. Mobile phone does not support information content: if your mobile phone does not support Chinese short messages, the other party sends short messages and your mobile phone displays garbled codes; Or the other party sent some pictures, but if your mobile phone doesn't support pictures, it will also display garbled codes. 2. Signal problem: If you are in a relatively hidden place and the signal is weak, you may receive incomplete information or display garbled codes.
