When AT&T eliminated unlimited data plans last year, existing customers had the choice to remain grandfathered under their current plan or switch to a 2GB or 200MB plan. But if you didn't take AT&T up on the opportunity then, you may still be in luck.
According to a report in USA Today, AT&T is allowing customers who had unlimited data plans in the past to return to an unlimited plan by calling AT&T Customer Service. This will be a welcome relief for those who find themselves using much more data than they expected on their iPhones. The unlimited plan costs $30 per month, while the 2GB plan is $25 and the 200MB plan is $15. If you go above your limit, AT&T socks you a $10 per gigabyte fee.
No doubt, this shift in strategy is related to the launch of the iPhone on Verizon with an unlimited data plan. Proof, yet again, that competition in the cell phone industry is a good thing for consumers.
