I am going to be living in Canada for the next 2 years. I need to add global roaming onto my account so I can actually use my phone. I am currently using the $35 a month plan. The website says to just go to my services, update my plan and that there will be an international/global tag for me to add this on, but I dont see one. Also on the website if I try to go to the global data page to learn more it says internal service error. What should I do next?
