On a two-week trip around mid-south Alberta Canada in July-August 2019, I used my Verizon Jetpack so-called "Unlimited" (actually unlimited up to 15G, then speed is severely limited).
Just wanted to advise people that Verizon's cellular data service in Alberta is frustrating. Not talking about phone-text, but Internet. It's not so much a problem getting signal. Signal is available, often a good strong signal. The problem seems to be that Verizon's Canadian partners (Bell, Rogers, Telus) may be putting Verizon users at the back of the line.
Whatever the reason, the experience is maddeningly unpredictable. Most of the time, Internet reception was extremely slow even with a good strong 4G signal, and even when I'm below my monthly 15GB high-speed quota. A one-hour video took about 3 hours to download for viewing later. Loading a normal web-page could take 4-5 minutes. Sometimes better, sometimes worse. Occasionally in the same location where such slow speeds happened in the evening, I would get a "window" of familiar, high-speed 4G in the early morning hours.
I'm just glad Canada is included in my plan. If I'd paid the high extra daily surcharge I would've really felt ripped off.
Next time I'll look into buying a local cell-data plan from a Canadian provider.
