The details on AT&T’s 2 new smart phone data plans

AT&T’s new smart phone data plans

Starting Monday, AT&T Inc. is replacing its current data plan with two new ones:

— The current plan provides unlimited data for $30 per month. If you’re a current customer, you can keep it.

— A new plan called DataPlus will provide 200 megabytes of data for $15 per month. If you go over, you pay another $15 for 200 more megabytes. AT&T says this plan will suffice for people who surf the Web, send e-mail and use applications like Facebook. The data allowance is enough for more than 1,000 e-mails, hundreds of Web pages and 20 minutes of streaming video.

— A plan called DataPro will provide two gigabytes of data per month (10 times more than DataPlus) for $25 per month. If you go over, you pay another $10 for one more gigabyte. AT&T says 98 percent of smart phone users use less than two gigabytes, which is the equivalent of more than three hours of streaming video.

The prices are in addition to the voice part of the plan, which costs at least $40 per month, plus taxes and fees that vary by jurisidiction. Data use over Wi-Fi does not count towards the limits.
