Hi
It WORKED, and I have till June 2010,
I just happened to unlock my T mobile phone today !
the 1-2 call Sim brought up Cingular network, I had to play with the network setting as it did not go thru the first few times,
but it finally worked,
thanks for your help, it seems others will need to do this too

PS....can I send text messages from my 1-2-call sim back to Thailand and will they be able to respond and I will recieve the text in California?
and what would 1-2-call charge for a text this way ?
