Hi. I have an iPhone 4 on the AT&T network. I cancelled my AT&T contract about 5 months ago and have been using the Google Voice app for a phone when I'm connected to wifi. I decided to upgrade to Straight Talk just recently and today I received my SIM card from ST. After putting in the SIM card, I am unable to create a new APN and when I go into Network in my Settings it says: "SIM not provisioned" I've looked at some videos and some other forums and haven't been provided with any information to lead beyond this point in setting up my Straight Talk shiz.
Any help would be appreciated!
