I have no idea. The cells are numbered, but I never saw that in a
phone.

Probably something queer to GSM. I've never owned a GSM phone, always
having been on CDMA since they took my AMPS (analog) away. Maybe the
GSM guys here can help with that.

Ah, answered my own question....(c;

Go to:

and you'll see your numbers on the GSM Mobile Network Codes...

I hate it when someone stumps me, which is often. I just HAVE to find
out. It's my nature, I suppose.

310 means United States.
The second numbers are the carrier.

www.mountainwireless.com has a wealth of information on cellular and PCS
systems. They work very hard to bring the latest lists, decoded to mere
customers can see why their damned digital phones won't connect to the
tower right in front of them while the phone reads NO SERVICE. It's a
great read these webpages.
