Hopefully, this will help someone out. We have 2 phones (iPhone 6 and 6 plus), with unlimited talk and text, 20GB under a 2 year contract with ATT. Our bill after taxes and fees is usually $175 (Includes 26% discount from my company). We were seriously considering switching to T-Mobile. I called ATT Cancelation and explained we wanted to switch because of the cost. TMobile is $100 plus taxes and fees and it included international data and text. The ATT agent offered to switch us to the NEXT plan (and release us from our contract). Since we have been under contract for over a year, we would own our IPhones outright. The only catch is they have to send us two Nokia phones that would cost us $5 month until we pay them off ($100 total, so 12 months payment). We can continue to use our IPhones, and don't have to use the Nokia phones. The bottom line: Nothing changes with our plan. Our bill will go from $175 to $138 a month. After we pay off the Nokia phones then our bills go to $128. I stayed on the phone for over 1.5 hours going through every possible loop hole or trap that I could think of! The only downside that I found was that we would lose the 25 GB of rollover data that we've built up. Obviously, that shouldn't be an issue since we never even get close to using 20GB a month. Again, hopefully this could help someone out. If you've done this and ended up regretting it, please let me know! Good luck.
