Pros: Can't think of any.
Cons: Dropped calls. No reception. Can't even consistently access voice mail from a land line.
Summary: I switched from Verizon because Verizon marketing was annoying. Big mistake. ATT services is garbage. No reception. Dropped calls. Can't even access my voice mail by a land line because of technical difficulties at ATT. Can't get a human on the phone to fix the problem. If you can actually talk to a person, they give you bullshit excuses.
I can almost never even make a call from my office at the highest elevation in heavily populated southern Baltimore county.
I'm way overdue to switch service.
