Hi, I live in Quebec, Canada and I have just got a new job that will take me to mexico for three months during the winter. Of course I will not be using my phone other than wifi over there as the roaming charges would be too costly for me. So my question is, can I halt my service for the three months so that my 3g would not work, I would not be charged for those 3 months? I don't want to choose a new plan when I unhalt the service. Thanks!
