Unlock the phone using my SIM card number.

I just bought a used HTC Radar 4G.

I reset everything and started updating it using Zune.

When the phone is connected to the computer,

I got a message saying my phone is locked and so unlock the phone using my SIM card number.

This is my first smartphone and third T-Mobile phone.

I have never been asked to insert the SIM card number except for the first one.

Without Zune, I cannot update my phone and others.
