AT&T continues to quickly hike the cost of unlimited data in order to drive its dwindling grandfathered unlimited data users to metered plans. Users in our forums say they're being notified of a $5 bump in the cost of unlimited data starting in March of 2017. The hike would be the second such hike in as many years, after AT&T bumped the cost of unlimited data last February.
"Our Mobile Share Advantage plans and our AT&T Unlimited Plan provide several benefits that our legacy unlimited plan doesn’t," AT&T said in a statement to DSLReports.com confirming the move.
"If you have a legacy unlimited data plan, you can keep it; however, beginning in March 2017, it will increase by $5 per month," AT&T said.
