AT&T Raising Price of Grandfathered Unlimited Data Plans to $45 Per Month
In the article, AT&T says that any customer who has a grandfathered $40 data plan will soon begin seeing an email about the $5 per month price increase. Multiple tipsters have already gotten such notifications, and one -- MacRumors forum user jav6454 -- says that his grandfathered unlimited data plan was originally bought for $30 around the time of the iPhone 3G.
The last time a $5/month increase happened was in March 2017, raising grandfathered plans from $35 to $40, and followed an increase from $30 to $35 in February 2016. AT&T originally discontinued unlimited plans in 2010 and didn't introduce new unlimited plans again until 2017.
In its explanation, AT&T says that "record levels" of mobile data use have led to the decision to increase the monthly cost of legacy data plans:
Consumers are using mobile data at record levels and the trend is expected to continue. To help make sure we continue to provide the best service for all of our customers, a small price increase is being made at this time.The carrier promises that the price increase will not impact data speeds, and speeds will only be reduced when 22GB of data in a billing cycle is exceeded or when users are in a congested area. AT&T also points out that customers can change their plan at any time, although anyone who switches out of a grandfathered plan should be warned because they won't be able to go back once a new plan is selected.
Customers who have a grandfathered $40 data plan will receive notifications of a $5 per month rate increase for the data plan. The rate increase will take effect starting with the customer’s July, 2018 service.
Currently, AT&T offers "Unlimited Plus Enhanced" and "Unlimited Choice Enhanced" as options for unlimited monthly data usage. Unlimited Plus is $80/month for one line and then rises to $190/month for four lines (at $48 per line), while Unlimited Choice is $65/month for one line and $160/month for four lines (at $40 per line). The latter plan streams standard definition video, lacks mobile hotspot features, and doesn't include DirecTV entertainment savings (only DirecTV Now).
Before these new unlimited plans launched, AT&T and many other carriers were heavily focused on eliminating grandfathered users through ongoing price hikes, like we are seeing again this summer.
