Best option for using my US smartphone in Canada?
I'm planning a 1-week visit to Canada (Vancouver, BC) later this summer, and I'm looking into options to be able to use my USA smartphone (HTC One) while I'm there. I currently have AT&T service (GSM), and primarily want data and texting service. I know that AT&T has special monthly add-on options for Canada, but they seem costly for a one week visit. Does anyone know if there are any other options? For example, can I buy a pre-paid or pay-as-you-go SIM card from a local Canada carrier and use it in my HTC One? If so, does my HTC One need to be "unlocked" to do this?
Thanks for your responses. I have a feeling that I probably will need to just not use my HTC One while in Canada, but I thought I'd ask to see if anyone has any good ideas!
