The only issue that iPhone users will run into is that even though you are allowed to upgrade your existing plan to this new service mid contract; you are still required to keep your $20 unlimited data plan. Hopefully all of you iPhone owners read the fine print that stated you were not only signing into a 2 year voice contract but also a seperate 2 year data contract. While $20 isn’t a lot when you think of how much this can save avid cell phone users, adding on another $20 for unlimited text messaging will bring you to a whopping $139 per month. If you’re a business professional on the go, this might be exactly what you need.

You can head on over to the AT&T website to change your existing plan. Simply sign into your account and change your voice calling plan to the newly listed “Unlimited” plan for $99. If you’re mid month, they will pro-rate the rest of your month so you shouldn’t end up paying more than $99 for the calling over all. I guess it’s time to say bye-bye to rollover minutes.
