I have an AT&T Lumia 920 and I decided to jump ship from AT&T and switch to Straight Talk, I'm tired of contracts. So I bought an AT&T compatible micro sim, put it in my phone and nothing... it says "invalid sim" and "no active network" I activated the sim and paid for service, I've tried googling it and it seems everyone else has no issue. I'm thinking it MIGHT be because I'm trying to port my number but I requested the port from the website yesterday around 4pm PST and it's now almost 24 hrs later and when I check Straight Talks website it still says porting in progress. Is this normal? How long does it take to port? Any ideas or suggestion on how to get this to work?? I changed the APN and such but now not even the time or date is correct on my phone. I really like this phone and i dont wanna get rid of it and i DONT wanna go back to AT&T!
