You said you think your operator is 31020.
Therefore please check it before entering and do not try entering multiple times. If it does not work, post here.

How do I find out the exact Network code? There are serveral codes for T-Modile in the US.

You can ask T-Mobile for the network code. Really :-)

310-20 should be correct, but the unlock code could need to be modified at the fifth digit.

I will try to resolve the issue and post agin.
