When ZTE Red Bull v5 mobile phone can't send and receive short messages after factory settings are restored, the system will prompt it to send after recovery.

If the mobile phone can't receive SMS/MMS, the memory is insufficient. It is suggested that you clean the memory of the mobile phone as follows:

1. Clean up the read call records and text messages in time.

2. Clear the Internet records of mobile phones: browser-menu key-settings-privacy security (privacy)-clear cache, clear history, etc.
