Had my first LTE connections here today. Seems spotty but have connected in several areas this afternoon. I don't actually seem to have data connectivity though....I sometimes got the "Could not activate cellular network" message even though I had full bars and the LTE symbol. Tried turning airplane mode on/off and even tried to reboot. Hoping its just part of the startup process and not a phone problem. Just turned off LTE in settings for now. Hoping things are fixed over the weekend. Anyone else in Minneapolis experiencing this? Any other markets just coming online?
