I have An ATT SIM in my Phone and its Home network is set to the old ATT
Cell Sites. Generally this is not an issue as the ATT cells cover my area
pretty good.

Though at my house, the ATT Cell Signal is poor to non-existent. The
Cingular Cell Signal is excellent! So what I'd like to do is set my 'home'
network to the Cingular Cells and not the ATT Cells.

Since the ATT Signal is weak, it drops out and then switches to Cingular,
then the ATT signal peaks again and then switches back. This switching
caused the battery to be drained rather quickly... Quite annoying...
Setting the Service Selection to manual makes it so when I'm home it works,
though traveling to and from places its always asking me to switch...

Thanks,
Scott<-

Hey Scott,

I have a similar situation. I have an ATT SIM Card that seeks the ol
ATT signal before seeking the Cingular signal. I also have lousy AT
reception in my home. (I believe the new Cingular 64K SIM Cards see
out whichever signal is strongest, but to get them you have to sign
new Cingular Contract...I am happy with my ATT Contract so have t
stick with the ATT SIM)

What I do is alter my Network Settings to read the Cingular signa
manually. In my area (Tampa Bay), the old ATT signal now displays a
'Cingular' on the phone, and the Cingular signal reads 'Cingula
Wireless'.

On the phone in Network Settings I have set the BAND to AUTO and th
TYPE to MANUAL. I then select the 'Cingular Wireless' network an
register it. I get 4 bars signal over 2 or 3 with the old ATT signal.

Just note, depending on your phone model (I have a Moto V551 quad band
you may have to reset the settings when you reboot (I leave mine on mos
of the time, even when charging). If you hit an area where there is n
Cingular signal, it may jump back to ATT signal, or the phone wil
alert you not signal is available. Then just flip the TYPE back t
auto.

Apparently the ATT SIM seeks the ATT signal 1st, even if it is weake
than the Cingular signal. So you have to manually overide that b
putting the phone to manually read Cingular. It works in my area
hopefully also in yours

Good Luck
