I was pleasantly surprised Verizon had free roaming to Canada… With 500MB per day of data. Not a lot for heavy users like me.
But don’t worry, you can pay $10 for 509 more megabytes!
I swapped to GoogleFi the next week. True roaming for no extra fees (just selling your soul to Google). It is amazing in Europe right now though. Just go and don’t think about your phone.
