I had bought a AT&T Tilt off ebay and in the States it works with my Cingular network. However when I travel as I am now in Greece and use the Cosmote SIM card it states that the SIM is not inserted and thus I am stuck. Cosmote runs on the 900/1800 network and Cingular runs on the 850/1900. The TyTn II is supposed to work on each and every frequency. It was supposed to be unlocked when I bought it but I don't know exactly what to do now.
The Card is not even recognized, this points more to a broken SIM Card. The TyTn Can operate in all these Frequenzies and would prompt an error that this device is locked to another network if it wasn't unlocked. So this error message is more like there is no SIM Card inserted.
Have you tried it in another phone? cleaned the metallic contacts of the Chip?
