[Q] samsung Skyrocket data LTE network issues

view story

http://forum.xda-developers.com – Hello, I just purchased a samsung 1727 actually my Infuse quit on me so my friends over at Asurion (At&t's insurance ppl) sent me the skyrocket as my replacement phone. My question is when I placed my personel SIM card and another sim (both have data plans btw) into the 1727 i noticed I didnt have a data network outside my wifi coverage area. This wasnt an issue with the infuse . Do I have to upgrade to an LTE sim card ? The rep at att.com said my old sim card isnt compatible with the NEW LTE network and she has to provision a new one so it will work in the 1727.. Does this mak (HowTos)
