What is the reason why you can't send text messages in groups?

1. SMS center number is not set correctly. For the telephone number of this center, please consult the network operator (10086 or 100 10).

2, mobile phone arrears, the solution is to pay.

3. The short message storage in the mobile phone is full, so it is impossible to store short messages or even information reports. The solution is to delete the text messages that have been read.

4. In the mobile phone settings, there is one item, that is, SMS setting network selection. I think this is probably the reason for your mobile phone: automatically choose &; Only GPRS network &; Only applicable to GMS network, if you only choose GPRS network, you will not be able to send SMS.
