A:AnswerHello, I would suggest you contact your service provider with regards to your options since there is a fee associated with a new activation as well as possible data change plans etc. Usually the sales price involves a new 2 year agreement with that said your best bet is to check with your carrier. If they are willing to work with you then at that point go to Best Buy and have those details ready. Personally I have gone direct to Best Buy and their associates are very knowledgeable and will likely call your provider for you.
