Of course, what I really needed was a working SIM card for my business trip, so I can't say this was satisfactory, but at least they made an effort to try to resolve the issue.

It's very good SIM card I used in USA and Canada, good signal and fast LTE.

The T-mobile SIM worked flawlessly in the US as well as Canada

The T-Mobile shop in the town he is in says it appears to be a fraudulent SIM card.

I'm cards from Amazon due to the lost of money and time I spent trying to unravel the mysterious practice of faulty sim cards

Much better than a Rogers SIM that I purchased for an earlier trip.
