Hey everyone. After the KitKat update for my S3 all my apps re-updated. In this process my APN's for Hangouts got screwed up and I was fishing around my phone trying to find them again. In this process I somehow screwed up my phones cell network. No idea what I did, but I preformed a factory reset, and still, nothing. My 4GLTE still works totally fine, my phone was auto-updating apps, I can browse Chrome and everything. But i cant make phone calls or send texts. Any ideas? Thanks in advance.
