My family bought 3 Iphone 5(s - plural) from T-mobile Store when it finally came out early this year in tmobile. Two whites (.5G and 2.5G data plans) and one black ( for myself unli data plan since im paying for all lol). Finally got my black iphone 5 unlock by tmobile today yey!!! Anyways here is my question , when we bought those iphones last year the two iphones have the hotspot enable and mine is not. Do you guys know why and how to enable the hotspot on my phone.?
