Answered question
with a regular unlimited talk plan, how much does it cost to use the cell phone in the usa
I'd recommend going with the US/Canada plan with unlimited Txt and Voice. It is very cheap compared to other companys. If you add 1GB of Data it comes to less then 35$
Good luck

This is the current cost for Canada/USA coverage for unlimited text and minutes (21.60$/month) :
Fizz price plan will be raised (about 39%) at the end of the stabilization period : https://fizz.ca/en/faq-stabilization-period
Add $6 to change plan to USA coverage, change back when you are in Canada.
