AT&T will raise the price of its grandfathered unlimited data plans from $30 to $35 in February of 2016, reports CNBC. The upcoming rate change is detailed on a page on AT&T's website and is the first price hike the unlimited plan has seen in seven years.

Though AT&T no longer offers unlimited data plans to customers, a small number of customers continue to hold unlimited data plans that were purchased before AT&T discontinued them in 2010. AT&T's current $30 unlimited data plan allows customers to use an unlimited amount of data, but AT&T does throttle with excessive data usage.



As of February 16, the $30 price tag, which is in addition to voice costs, will rise to $35. The price hike comes just a couple of months after AT&T announced changes to its throttling practices. AT&T previously throttled customers on congested networks after 5GB of LTE data usage, but that cap was increased to 22GB in September, making unlimited plans more valuable.

AT&T plans to notify customers who will be impacted by the price increase. Customers who wish to cancel their wireless service because of the pricing increase will have early termination fees waived for affected lines. Price changes will take effect during each customer's February billing period.
