@vihru you ever tried to reboot? Are you also sure that your device version supports the 4G bands?
Please also give us your firmware version.

i have experienced something similar
choosing 4g disables network completely
i think flyme 5 has problems with network
try flyme 4.2

also i am reading that the camera is a lot better in flyme 4 compared to flyme 5

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
