I've been running the numbers, did the T-mobile test drive in LA and I am planning on making the switch to T-mobile after the iPhone 6 is released. A 5 person family plan on T-mobile is $110 a month, or $22 a line. My Verizon plan is $60 a month per line with 2gb of data a month - if you split out the phone subsidies, around $20 a month per line, that's $40 a month per line. Technically the T-mobile plan only includes 1gb of data at LTE speeds (2.5gb through 2015) but I can increase to 3gb for an extra $10 a month. I rarely go over 1gb anyways as I have wifi access at home and work. If I can get more family to switch, at 8 lines it is $140 total or $17.50 per line. This seems like a fantastic deal. I also tried the T-mobile test drive in the LA area and, at least for me, I had better data speeds and good call strength. Verizon' network out here seems congested and slow, T-mobile was much stronger with faster data speeds nearly everywhere I tested. Who else is taking advantage of the T-mobile family plan come iPhone 6 launch?
