Android stuck on roaming mode
Try Switching your network mode to manual head over to the Settings>Under wirless and networks> tap more settings>Mobile Networks> Network operator> Search for the Network again now after searching select the appropriate network. This keeps happening with my device too there are actually two Mobile Networks, it usually arises because you may be living in border and somehow the signals from other Lycan network, I am sure you are doing the same, I know its weird but I guess you can't help it its up to you carrier, you could give them a call about it.
