The enhanced version of Red Rice Note4G bought in Tmall official website the day before yesterday cannot be activated by inserting the SIM card. It can't reactivate free SMS. What happened?

I suggest that you back up important data first, then restore and clear all data, and don't restore data temporarily after booting, and see if you can solve the problem. (Backup: Security Center-Backup, backup the data you need. Clear data: press and hold the volume up button and the power off button when the boot screen appears, and then let go to resume. Enter Recovery & gt Chinese > clear data > clear all data. )
