Finally, I got some straight answers from someone at T-mobile. I guess the plan is so new that not everyone understands all the details.
OK yes as pointed out by lawrosa, the data is unlimited, but the speed is not. At US$50 per month, the plan includes 1GB of 4G/LTE and if you exceed that, the speed goes down to 2G. But as I say, the data plan is of less concern because I rarely use more than 1GB on my Rogers smartphone. And for another $10 per month I can get 3BG of 4G LTE. This just blows Canadian data rates outta the water.
While I am in the US, any unused 4G/LTE capacity rolls over to the next month and accumulates for use within 12 months. I can use that stashed data while in Canada but it will not continue to accumulate while I am in Canada.
When they say "Unlimited talk, text and data while on our network" that means their extended network including service providers in Canada and the US with whom they are partnered. So calls between my number and US numbers and Canadian numbers are not "roaming" no matter where I am in Canada or the USA. Or Mexico, for that matter, but I doubt I will find myself in Mexico in this lifetime.
The customer service rep did say it was a limited time offering, but once signed up to this plan it would not change. Mind you, if for any reason I don't like what I am getting for my money I can cancel because there is no contract.
If I want to suspend the T-Mobile service while I am in Canada, I can do so for up to 90 days and pay only $10 per month.
Wish me luck, folks! I'm going in!
