AT&T boosts data limits for prepaid smartphones AT&T boosts data limits for prepaid smartphones - Tech and gadgets GoPhone customers will get 1GB of data a month, enough for the basics AT&T Wednesday announced new data packages for its GoPhone customers, the company's line of prepaid phones. AT&T has tripled its prepaid data without raising the price - a novelty in today's world of ever-rising prices. The plans will be available beginning April 22. But don't get too excited. The maximum amount of data on an AT&T GoPhone has been raised to 1GB, about enough to handle email, Facebook, surfing the Web and sending a couple of photos each month. Still, that's more than triple the stingy amount of data previously available to GoPhone customers - 300MB - and at the same price of $25 per month. AT&T added smaller data plans as well, including 200MB for $15 and 50MB for $5 - just enough to handle your email. The data packages are available as add-ons to the $50 unlimited talk and text plan as well as the $25 unlimited text with 250 minutes talk. Wondering how AT&T prepaid plans compare with its competitors' plans? Take a look at our "Smartphone Data Plans: Ultimate Guide." Smartphones are a pretty new addition to AT&T's no-contract options. Just a year ago, the company launched its first prepaid Android smartphone, the LG Thrive. Currently, AT&T offers around 10 smartphones, including Samsung's Captivate and Double Time models with the Android operating system.
