Might be your phone, I'm in Portland, OR as well and like I said, rarely ever get dropped calls with ATT. With T-Mobile, completely different story.I assume Oregon...and a note of my experience. I have full bars, yet I still get dropped or distorted calls all the time. The call will go fuzzy all of a sudden, yet the signal still shows it as being great. I will not be renewing with AT&T when my contract's up.
