Wow, talk about highjacking a thread. This was about cell phone coverage. If you folks want to argue the days allowed to visit the US, you should start another posting.
I have a Rogers phone without a contract. When I head to the US, I change my phone to pay as you go for $10.00 and then don't use it. I do this to preserve my phone number and stop all charges from Rogers. The $10 is a one time fee. I then go to AT&T and get a plan for $60 per mo US which gives me unlimited calls to Can. and texting. Also included is unlimited data. You get 8 gb of data (lots) per month then it slows down but 8 gb is a lot of data. I use the phone as a "hot spot" for my computer and it's much faster than the park wi-fi. If you don't use all your data in the current month, the balance rolls over to the next month.
Soon as I get back to Canada, I call Rogers and get back on a monthly plan. I never sign up for any contracts. I give my new phone number to relatives (some of them) and friends when in the US and don't worry about anyone else calling me while I'm in the US.
Having a working phone with data when you travel is very handy for checking places to stay and Gas Buddy for fuel prices as well as road conditions etc.
Canadians are getting screwed by cell phone companies thanks to the CRTC.
