Why can't Shenzhouxing send text messages? Thank you.

There are several ways to solve this problem: 1. Try making a phone call. If you can't make a call, it's the signal problem of your mobile phone (the signal involves two aspects: the signal problem of the mobile phone itself and the signal problem of the operator). 2. Try to restore the factory settings. 3. Check the number of SMS information center and move it to +86 13800XYZ500(XYZ is the area code, Wuxi 05 10, XYZ is 5 10, Suzhou 05 12, XYZ is 5 12, Nanjing 00. 4. Some minor settings: whether to enable GPRS: No, message sending format: text format. Wait, wait, wait (depending on different models of mobile phones) 5. All the above solutions are useless. You have to go to the mobile phone maintenance department. This is a problem with your mobile phone hardware or system software.
