-updated & SOLVED: Chinese M3s (5"screen octacore with FLYME 220.127.116.11A) doesn't go on 4g/LTE in Italy
@faredino2 I guess that you have double-checked your cellular settings.
But just in case, then check Settings->Cellular Networks->Network Mode. Make sure this option is set to ‘4G first’ and not ‘3G first’.
