I have four lines on my mobile phone plan, and with TMO I am paying about $195 for everything. My parents have "dumb" phones and I think they like that... my wife and I have smartphones. I'm switching to AT&T because I get a 20% discount, and I also want the Lumia 920 for the camera/build quality for both my wife and myself. Question is... what do I do with my parents? I don't want to add them into my plan because of the contract, but then MVNOs don't seem to be that cheap either. Any suggestions folks? Thanks!
