Terrible Experience with AT&T – Stay AwayWe left T-Mobile for what seemed like a great deal at Costco—free phone upgrades and a promised $180/month bill. Instead, we were hit with $300+ bills and terrible service.The phones constantly lose signal, making it feel like we’re out of the country. I’ve gotten lost multiple times because GPS failed.AT&T also charges extra for faster internet speeds, which was never mentioned when we signed up. Customer service has been no help.Save your money and peace of mind—don’t fall for their misleading offers.
