Zte v880 can't send text messages. The center number is correct (set to *#*#4636#*#*), and China Unicom has been contacted. ...

First of all, I suggest you change your mobile phone card to another mobile phone and test it to see if it can be used. If it can be used, it proves that there is something wrong with the settings or hardware of ZTE v880 mobile phone. Check the SMS center number in the SMS settings of the tested mobile phone and record it for use. If not, you can call customer service 10 10.

If the test mobile phone can be used, please re-check and fill in the SMS center number in ZTE mobile phone. You can directly check the settings in the text message-try filling in the center number.

If it still doesn't work, you can't use this card to send text messages, so you need to check whether there is a problem with the SIM card (you need to check the SIM card) and whether the mobile phone is faulty (ask for professional knowledge or mobile phone customer service to provide technical support). I hope I can help you!
