So, I go on app and pay my wireless phone bill. Its 2 line unlimited everything which I've been on for years. Then, I read that if I dont change to a newer plan each line will be $5.00 higher starting next bill.

How can they just decide to retire my plan? I know its their corporation but thought I was grandfathered in on my plan.

Has anyone else's plan been "retire" by AT&T recently?
