My experience:
Set up a T-Mob account for intl data roaming as a Canadian in a US T-Mob store; no problem. (2013)
6 months later my phone number account was terminated due to not using the account in the US enough compared to the intl usage to qualify. The agent I talked to mentioned that according to their records my "SIM" has not locked onto any US towers enough times compared to my intl usage.
