Just yesterday I learned that AT&T is adding a bonus to their 10GB data plan. New and current 10GB data plan customers will get an additional 5GB toward their bucket. This seems like a great deal to me and I plan to sign up for it. All you have to do is call 611 from your AT&T phone or go to ATT.com. Here’s a link to the release.
By the way, according to AT&T you can do all of this with the 15GB:
Stream 160 hours of music and 30 hours of video
Surf the web for 300 hours
1,000 posts with photos on social media
Download 100 mobile apps
Send/receive 10,000 emails
