Send Sony Ericsson 580 SMS to remind me what's wrong with no network signal? How to solve the problem?

The signal in your area is not very good, but my W580C won't. If the mobile phone is in an emergency call state, the information you write will not be sent first, but will be saved and automatically sent when there is a signal.

Is it possible that your mobile phone is in arrears? When sending a message, the letter e will be in the upper left corner of the screen, and the letter g will be in the upper left corner of the screen in the state of emergency call, and sometimes there will be no letters in the upper left corner.
