I have a At&t 7780 phone here. I got into the options and select "Network" then change it to "Manual" and hit "Scan"
I am presented with
* AT&T Wireless
* Cingular Wireless
AT&T gives me 4 bars of service
Cingular gives me 2 bars of service
T-Mobile gives me SOS
There have been problems with Cingular since Wednesday afternoon. The SOS is one of them. I had been getting this on my office and there is no Tmobile signal at all here. Cingular has acknowledged since my first calls to them on Wednesday that there have been major problems. BTW....I still get SOS on occasion, but a Wireless off/on generally clears it.
