Please tell me why I can’t receive text messages on Samsung note 2

1. Restart your phone to see if it is a signal problem.

2. Try changing other SIM cards

3. Check whether the security guard or third-party SMS software is installed on the phone, uninstall it and test

4. Back up your phone's data (phone book, text messages, multimedia files, etc.) and restore factory settings

If the above methods still don't work, please send the device to a Samsung service center, where engineers will check the machine and handle it.
