I am new to AT&T coming over from Sprint. I use my phone in northern Wisconsin just about every weekend. When I am up there I would have thought that I would switch to roaming but instead I go down to about 2 bars and my 4G data signal will switch to Edge.
When it switches to Edge am I still on the AT&T network or is that my signal that I am roaming?
I have an Atrix HD phone.
