I was able to successfully unlock a Nokia 3390b T-Mobile, but, when I insert my Cingular Sim card, everything works fine but I get no signal? It came up 'Sim Restriction Off' like it was supposed to after the unlock code was entered, but no signal. :???:
I have tested all four codes for restrictions and they all report "Sim Restriction Off". So why can I not get a signal. The sim card is from a Nokia 3595. I have that in this 3390. It recognizes the Sim card but "NO SIGNAL".
Any help would be great.........................
