I actually thought there were other companies that had done this before AT&T.
A couple years back T Mobile started treating all of the USA, Mexico and Canada as a single service area. You just use your phone, its all included. This subsequently forced Verizon and ATT to throttle back on some of their abusive overage charges, but if you listen to their ads, it sounds like they still have 'got you' clauses in the contracts (like they are still run by bean counters that can't really quit screwing their customers) .
Around the time T-Mobile started this, back in the hey day of 'got you' charges at the big carriers, I had a friend who's plane out of Cancun returned to field and he pulled out his ATT phone and spoke with Alaskan customer service for about 20-30 minutes getting his down line flights straightened out, as a loyal ATT customer for many years he got hit with a $240 bill.
I have used my T-Mobile phone all over Mexico and multiple trips into Canada, never have I been charged for calls or data, I just pull out my phone and use it (including local #'s via the international calling exchange). I visited Curacao and had free roaming data and free WiFi calls a couple months back. Last night I got back from a couple days in Zacatecas MX, phone worked when ever I needed voice or data.
I have 3 lines of unlimited data and calling plus 10 G tethering on each and the total bill (all in) is $100 a month.
