I bought 3 moto g's and on the day they arrived switched the entire family to tmobile. I had enough of Verizon and now my bill is $100 a month. Can't beat that.
I would like to leave VZ too, but I'm simply too afraid that the coverage will not be there on tmobile and at&t - and especially I need to consider the WAF.
I understand. Coverage was what kept me on VZ for 10 years. What finally got to me was the fact that when I'm overseas I can just swap a sim and T-mobile's coverage has been improving exponentially.
There's only one family plan on the T-Mobile site now, called Simple Choice. It's $80/mo for 2 lines with unlimited talk + text + web (500MB at 4G per phone then slower speed), and $10/mo for each line after that. There's no contract or credit check, and you either bring your phone or buy one from them -- unsubsidized but payment plans available.
