First you have to at least add international calling feature. You can do this over the phone with them. You will have to update the roaming (*228) afterwards. If you have a data phone and don’t want to receive data, make sure you uncheck the data when roaming or it will cost you. Cost mentioned above is right on. I personally liked not having to check my email and I have to say I didn’t think of it anyways since so much else was going on!
called and verified today, apparently, I'm switching to the Mexico nationwide plan for the 10 days i'm there...different dialing pattern for calls and texts 01152+landline # and 011521+cellphone #, and it's going to cost me $39.
