Help: Who can tell me how to solve the problem that Nokia N79 always can't send short messages! ! ! !

There are several situations in which text messages cannot be sent out. You should deal with these situations:

1: The software version is too low and the system is unstable. Go to customer service to upgrade.

2. If you change your mobile phone card frequently, check whether there are multiple information center codes in SMS-Options-SMS Center. If there are many, delete the useless information center code on your card.

3. If the above two are all right, and the mobile phone version is the latest, it is necessary to back up the phone number and other information, and then *#7370# restore the mobile phone factory settings. If you have downloaded the third-party software from the memory card, it is also recommended that you back up the important data of the memory card and format the memory card (some third-party software will conflict). In this way, your mobile phone and card are in the factory state, and there is a problem that is the fourth type.

You said that other people's cards can be sent on your mobile phone, but your cards can't be sent on other people's mobile phones. Obviously, there is something wrong with your mobile phone card. Go to the mobile company to get a new card.
