[Q] Out of service area topic

My M2 has full HSDPA signal on the correct network but every time I try to call out I get a half second flash of "Out Of Service Area" its not rooted fully stock any ideas how I can six this? It gets signal with multiple simcards. Also can't receive calls or texts. I'm can root if it can fix the problem.

Any help is much appreciated
Thanks
