With 3 out of 5 signal bars and 4G service, looks like my phone has detected a lack of 4G so it's moved over to 3G, yet while texting and attempting to send an image via regular SMS, the available bandwidth is so bad that I feel as though I am being throttled to a standstill. Amazing that we have to accept this as "service." And I am located 5 miles away from the Pittsburgh International airport and less than 5 miles from the center of town, a business center. You would expect much better service coverage and performance in this type of environment.
