I empathize with gospace but the wireless customer agreement says AT&T can change anything anytime they want. If it's a material change that you're negatively affected by they notify you in writing and you may cancel without etf. That's exactly what they did. That's not to say I think it's fair, they're just not breaking any laws or even their own terms of service.

As for T-mobile customers they will probably some changes that require customers to change their plans. That has been the case for all the prior mergers.

That being said prices have been dropping for a LONG time. There are still of lot of grandfathered plans on AT&T from prior mergers. There was a period where the old plans were cheaper because prices went up when plans went from regional to nationwide but those plans are garbage compared to current offerings.
