AT&T has implemented a workaround to allow existing GoPhone Pick Your Plan customers to use Apple’s iPhone without needing to sign up for a new line of service.
Due to limitations in the iTunes-AT&T activation server, GoPhone accounts that were set up outside of iTunes were unable to add an iPhone to their account. This meant that GoPhone account holders would have to abandon their existing mobile number, or go through an elaborate porting mess (porting a number out of AT&T to a third-party prepaid service, setting up iPhone on a new GoPhone account, and then porting the number back over it).
Thankfully, the process has been made rather simple. GoPhone users simply need to call 611, and at the prompt ask to Add Features. Saying “iPhone” at the prompt brings up an offer to attach the iPhone $19.99 bundle (which adds unlimited MEdia Net and Visual Voicemail). As soon as the change takes effect (at the start of the next billing cycle), you can connect your iPhone to iTunes and complete activation.
Unfortunately, PhoneNews.com has found AT&T Customer Care to be extremely uninformed on this process. Every GoPhone customer care representative we spoke to on multiple calls was unaware that this was the process to add GoPhone to an existing account. Most either generically told us to connect iPhone to iTunes (a non-starter for GoPhone users), or that it simply could not be done.
