Hi. So I have never had a good smartphone before. I have only had cheap tracfones that don't work well. I am going to college this year, and I am getting an iPhone 6s. I was wondering how many GB of storage I should get. 16 seems like it won't be enough (My ipad mini is always running out of storage), but 64 and 128 can get expensive. What is the ideal number of gbs for a college student? Also, can anyone recommend a certain carrier (unlimited talk, text, data). I've heard sprint and t-mobile are good. Thanks!
