Hi,
I have an iPhone4 with firmware 5.1.1 and I just ported my number from AT&T to StraightTalk. However, in the past I purchased the Straight Talk service for a month to try it out before switching over and I just needed to pop my SIM Card into my phone and it would automatically detect the new network and would display "HOME" instead of "AT&T". But today, the porting is complete and it just says: "No Service".
What can be the problem and how can I fix it?
Thanks!
