May 29, 2026 My internet provider has been very reliable and consistent. I have used it on the go in many locations and it has rarely let me down. I am a very satisfied customer of AT&T and have nothing but praise for the service provided and the price point. I would highly recommend this service to everyone I know.
Dustin B.
Midco Fixed Wireless
April 14, 2026 They have good service, but their pricing is beyond sane. Basic cable runs $60 each room so to have basic cable in my home would cost $180. FOr basic cable. Basic non Wi Fi internet starts at $60 month. It's absolutely nuts how much it costs.
