Forgot to post my experience with the new Simple Choice North America but I just got back from PVR and had LTE everywhere I went including a couple miles out into the Bahia de Banderas. Also had 3G show & work well on my phone in a couple areas where the coverage map showed no coverage. So that was a nice surprise!

At the resort where I stayed & along the Malecon I was stopped a couple of times by fellow Americans who wanted to be good Samaritans and let me know it would be way too expensive to use my phone in Mexico. I laughed, said its free with T-Mobile and got some interesting reactions. I was quite literally a walking, talking billboard for T-Mobile all week long.
