Unfortunately they used to have a plan you can use in both Canada and the US but that was quite awhile ago and was grandfathered in and those customers have been saying they have had some issues due to the 3G situation in the US, a local prepaid sim and/or voip apps may be more reliable and cost effective.
I changed my plan to have the unlimited Canada/US plan and now I’m in New York City and nothing works.
I got no data, no phone or text but have been paying for this plan the last 2 months.
I’m not impressed.
Am I supposed to do something to activate it when I change country?
Sorry, but this plan does not include usage in the United States. None of Public Mobile's currently offered plans have that. To use your Pubilc Mobile services in NYC, you're going to need to purchase a roaming add-on.
