The floor is yours!

I have been a member since last 2 weeks and the service is quite nice. More widespread VoLTE (call quality) and Wifi calling can be icing on the cake!

I am new to fizz and have a few questions. We plan on possibly doing some travel in the USA for a period of less than 3 months each (I am aware of the 3 month time limitation) and want to know what is the best plan for us.

1/ If I purchase the Canada/USA plan does that give me data, text as well as voice calls in the USA without any roaming charges?
2/ Can I change my plan from a Canada only plan to the Canada/USA plan for a couple of months and then change it back after we return to Canada? If so is there a charge change the plan?
3/ If I purchase the Canada/USA plan, is there any benefit to purchasing the USA roaming plan as well?
4/ If I purchase the USA roaming package, is this something I can do for a month or two or do I need to it permanently be on my plan and pay for it even though I am not in the US for most of the year?

Apologies ahead of time if these are deemed “stupid” questions, I just want to be clear about the difference between the plans before I commit.

Thanks in advance.
