Samsung only has three short messages left every day, and the others are lost for no reason. Why?

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

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

2. Try to replace another SIM card.

3. Try to update the next system version.

4. 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.
