Can anyone tell me if an LG CU500 can be used on Cellular One?
I have tried 2 of them now, purchased from eBay. Both were Cingular phones advertised to be "unlocked". The 1st one, a new phone, just came up with "Network unavailable" when I tried to make a call. The SIM card was from a RAZR I was using on Cellular One. The 2nd one, a used phone, with the same SIM card, actually displaed "Cellular One" on the screen after I enabled wireless on it, but it also displayed "Network unavailable" when I tried to place a call. The screen also no longer displayed "Cellular One". Now the SIM card doesn't even work in the RAZR.

To answer your question, the person sold you an LG CU500 that is still locked to AT&T. Anytime you put a SIM card in the phone and it won't hit any type of signal, it is more than likely locked. And as to why they ain't put you through to us in Tier-2 kinda strange. I could've at least answered the question about your problem right off the bat.
