I was under the impression that with my "Go Unlimited" Verizon plan, I could use data in Canada or Mexico at no additional charge. However, on a trip to Canada over President's Day weekend I was notified of having racked up over $50 in charges for international data. I immediately turned off my phone for the remainder of the trip and did notice the data charges on my billing cycle. I thought Canada data roaming was included in my plan.. has anyone else been charged? Did I miss something?
