I went from Verizon to pre-paid Verizon on Net10. $86 a month including taxes for 2 lines ($43 per line) unlimited talk text and 3gb LTE data each. For the $$ and coverage you can't beat it.
TMobile is great if you leave the country. I do, and still value my US coverage over their int'l coverage. The big joke is their coverage is far superior outside the country than in it.
