A:AnswerThey should, depending on the store it was advertised in. Anything like Fry's, Walmart, or Target are definitely on the list of stores they will price match to. I used to work at Best Buy.
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.
A:AnswerAccording to Straight Talk's website, you can bring your phone from almost all of the major networks, so it doesn't matter if the 5S started on AT&T, Verizon, Sprint, etc. All you have to do is purchase the SIM from them and configure the new surface. However, if the phone is in a contract with a network, you will most likely have to terminate the contract and pay the fee before you can switch to Straight Talk.
