I currently have T-Mobile but the service has been really bad where I live and I have 5 unlocked iPhones that I own. I was planning on moving all 5 lines to ATT for their unlimited data which is $220 a month before taxes. Do you think ATT will run any promos when the iPhone 7 drops. T-Mobile for sure will but I just can't stay with them any longer. Also do you guys think 5 lines $220 is a good deal for unlimited everything on ATT?
