So lately I've been struggling on 3g data connections.I checked my sim and its on a right slot too and my apn settings are fine too.The problem is I cant change my network from gsm to wcdma like on other mi phones. When i go to prefered network mode it shows(Ive posted a photo too).
USSD code isnt working either.
p.s My device is MIUI
