It's pretty simple, on which carrier is your iPhone 5s running? I'm curious as it seems that since Verizon and at&t have put the kibosh on unlimited data that more and more people are migrating to Sprint, T-Mobile, Prepaid, and regional carriers.
I'm on Verizon, but with grandfathered unlimited data on all of our lines (thankfully).
