I am currently with AT&T and I would like to port over to MetroPCS. I take with me 4 lines of service so I would like to take advantage of the 4/100 lines. Right now I pay the majority of bill for my family and this plan seems to be an option that I can tell them to pitch in a little more as I am tired of paying the fees at AT&T. My question is what if my family member decided to cancel the service at the end of the first month after porting over are there any ramifications? I think that one or 2 of the lines may have issues so they may want to go back to AT&T which at that point its not my problem. I know they offer free phones so if I get the free phone would I have to return it, can I keep it? Any information past experiences would be helpful.
