Why can't note2 messages be sent out, or even the received messages disappear automatically?

According to your description, I suggest you try the following methods:

1. Restart the phone to see if there is a signal problem.

2. I suggest you call the operator's customer service number to check whether the number of this SMS center in your area is correct.

3. Try to replace another SIM card.

4. Check whether the mobile phone is equipped with security guards or third-party SMS software, and test it after unloading.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the above method still fails, please send the equipment to Samsung Service Center, and the engineer will check the machine and deal with it. Please click the following link to find out the specific location of Samsung Service Center:.
