Sprint is offering free calling and texting while in Canada, and also from the US to Canada

I was playing with my Sprint account last night and found this: Sprint OpenWorld. If you have Sprint service and a dual band capable (CDMA+GSM) phone like a Galaxy S5, you can enable this on your account and get free calling and texting while in Canada (and most of North America) and also 1GB of data per month for free. Yes free. I called Sprint and made absolutely sure that I would not be charged for any phone calls I made in Canada and they confirmed it. Also, you can call Canada numbers from the US with this service and you don't pay a dime. Thought I would pass this info on to save others some money. Go to your account, go to "Change services for this device" next to your phone, and it should be the top two options in the list.

Cheers!

Edit: Did some checking around and it looks like T-Mobile is the only other US carrier that offers a plan with free roaming in Canada/Mexico.
