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.

Back in the early days of the iPhone, success for AT&T was no guarantee. To help bring customers to the fold, AT&T offered unlimited data plans for a limited time.

These plans have been “grandfathered” since then, but AT&T has made a number of efforts to wean customers off those unlimited plans to more traditional metered data plans. These efforts continue with the coming $5 per month bump.
