Default Re: At&t

ATT is currently set (in most areas) to hand DOWN from 3G to 2G if you are making a call. This leaves more resources for DATA on UMTS. Text MSG's try and go 2G if possible also. These are all carrier settings that they adjust in response to traffic demand. Keep in mind that 3G UMTS is 100% a noise driven network You can have signal from multiple sites but if the signal to noise is too high you will not setup a connection.
