Why can’t China Unicom and Telecom mobile phones receive text messages? What’s the reason?

It is recommended to operate as follows:

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

2. Settings-Application Manager-Sliding Screen Options (All)-Find Information-Click to enter, clear data and try again

3. Try changing other SIM cards< /p>

4. Check whether the security guard or third-party SMS software is installed on the phone and test after uninstalling it

5. Back up the phone data (phone book, text messages, multimedia files, etc.) and restore Factory settings

If the above method still does not work, please send the machine to a Samsung service center, and an engineer will check the machine and handle it.
