So I've been to many stores looking for a SIM card for my old iPhone 5S. Went to Best Buy a few other stores and nobody had it. I should have known to just come straight to the actual T-Mobile store. obviously they would have it if anyone would. the staff was very helpful friendly Enterprise is average where you would find it at any other store that carried it. I'm just happy to finally have gotten the SIM card I needed for my old iPhone and now I can play around with it and use it for music TV shows movies Etc.
