AT&T has the worst lousy service and too expensive. Billing is tricky. It is much cheaper to buy your own phone to avoid expensive data plan.
Unfortunately, Americans do not have much choice. Cut your AT&T landline phone and video service with nothing but junks. Save yourselves $150/mo.
Their uverse is awesome. For 30$/ month you get internet/phone/tv/movies etc. Unbelievable.
My landline phone service was over twice that. No I do not work for att. I have a small position in the stock and will be looking to add. I hope it crashes big!
