I know that in Canada, carriers can roam on each other in some places (ie. Rogers can roam on Bell in Sask, and Bell can roam on MTS/Rogers in Manitoba).
The question that I have is... can T-Mobile roam on TBayTel in North Western Ontario (eg. White River, Sioux Narrows, etc).

Greetings, looking at Ontario, it appears the roaming partner is listed as "Bell Canada" in the areas there is coverage. 😊 So anything Rogers or Rogers partner wouldn't connect, explaining why you may have been das boot.
