Currently I have a Verizon GS3. Like the phone a lot, however miss how well my iPhone syncs with my other apple products. I have a trade offer for my Galaxy S3 for an iPhone 5. My issue however is that I am have a Verizon Concession line through best buy and currently they will not activate iPhone 5's on my these lines. I just ordered a sim cutter on ebay. If I put my already active LTE sim card into an iPhone after cutting it down to a nano sim will it work and be active with my number, or will I have to still get it activated?
