In Feb, around the statement time, we all got TXT about excessive international roaming. So they are watching you even if you just signed up. I only roam about 2 to 3 times a year, so it wasn't a problem for me. But if you travel a lot, it could be a problem with T-Mobile.
New signups using international roaming is monitored by most carriers and MVNO’s. Another forum, I frequent has had discussions about new activations being flagged when roaming in Canada and Mexico from US numbers.
