The Atrix will roam onto the Microcell just fine. But after a while, it will disconnect from the Microcell and not connect to anything else.
I do have AT&T service at my house (but the cell sites around me are overloaded.)
When connected to the Microcell, I get 4 or 5 bars. But sometimes when I check my phone, it will not be connected to any network (except WiFi.) To get it to connect to anything, I have to switch to airplane mode and back, or reboot the phone.
When I am at work (ie. not near a Microcell) I seem to have no issues.
When the phone is not connected, I can't make or receive any calls.
Anyone have any suggestions?
(The symptoms look very much like the IOS5 issue, except this is Android 2.3.4.)
