I just got a 920 I kept getting a sim card error and,the phone was supposed to be unlocked. Now reseting phone by powering,off and on sometimes fixes it and,my,carrier shows up. But it always drops it.
My phone has the black update fyi
I read and,I changed automatic network selection to manual and selected my carrier. So far so good. With the notification bar hiding I never see if it connects lte, I only ever see 3g but at least the signal never drops...it,would drop and not reconnect once every half hour..
