Re: What carrier are you using and why?
almost all carriers claim to be the best. I would suggest you ask people in your area or places you go to about the quality of service from their carrier. As for ATT, they work in my area but lately I have noticed delays in making calls and accessing the data .
New York city area.
It may be due to demand and just plain overload on the cell sites.
