Note 2 SMS cannot be sent and received.

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

1. Restart the phone and check whether it is a signal problem.

2. Check whether there is any arrears.

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

4. Try to replace another SIM card.

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

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

If there are still problems through the above methods, please send the equipment to Samsung Service Center, and the engineer will check the machine and deal with it.
