B.C. Canada verizon service to U.S.

Getting a local phone from Rogers, Bell or Telus.

Your Verizon phone will work in BC on either Bell Mobility or Telus Mobility but you will likely pay high roaming costs. If you're going to be there for a short amount of time you're probably be better off getting a local calling card and make calls from a regular phone.

 

I beg to differ:

Enter your location

 

That link is useless for the OP's purpose since they want you to enter a US ZIP code. That won't help you if you're in BC.

 

You're kidding, right?
It's asking you for a zip code to see if you can sign up for VZW service. The page brings you to the Nationwide plus Canada plans, which cost $20 more than regular Nationwide plans and include calls TO and FROM Canada.
Since the OP is in Maine and already has VZW service, the page is not useless, and the Nationwide plus Canada plan is cheaper than any alternative mentioned.
