Avoid AT&T at all cost, especially if you a business owner. Alot of your calls will not go through, only way I found out is my brother and lawyer tried to call and they had the sense to text me to let me know they tried to call, and at&t wants examples and when the lawyer called, they said they couldn't find any issues, exactly, it's because they can't fix the problem, SO DO NOT USE AT&T. Use any other service. Because you have a phone so that you can call and receive calls and AT&T does not provide that and their corporate office doesn't care. They will pretend to work on your case and then say they can't help you because they can't find the problem.
