AT&T data plan pricing, details

AT&T is dropping its $30-a-month unlimited data plan as of Monday and replacing it with a two-tier pricing system for new customers. Current AT&T customers with unlimited data plans can stick with them.

Here are AT&T’s estimates for how much a user will get out of the data allotments in the new plans. The amount can vary greatly, however. For example, one e-mail with five high-resolution photo attachments could use up 5% of the monthly allotment on the DataPlus plan.

• DataPlus plan: $15 a month for 200 megabytes of data. AT&T estimates that that’s enough to send or receive 1,000 e-mails without attachments, plus send or receive 150 e-mails with attachments, view 400 Web pages, post 50 photos on social-media websites and watch 20 minutes of streaming video.

• DataPro plan: $25 a month for 2 gigabytes of data. AT&T says that’s enough to send or receive 10,000 e-mails without attachments, plus send or receive 1,500 e-mails with attachments, view 4,000 Web pages, post 500 photos to social-media websites and watch 200 minutes of streaming video.
