How did you unlocked the phone?

 

This is the information provided by the vendor who I bought the unlock code.

Model:  All HTC Model

1.    Insert an Unauthorized Sim Card and turn ON your phone

2.    Phone will ask "SIM Network Unlock Code"

3.    Enter Unlock Code

Model:  Verizon Droid Incredible 2

1.    Select Settings

2.    Security

3.    Disable SIM Card Lock

4.    Enter Unlock Code

I searched the mit bbs and found something. It mentioned unlock the network, not the call."我经历过，你改的可能是network里的GSM，不是Call里的GSM。" "我记得也是，改了 network 里面 GSM 以后不行，call 里面改了就可以了，network 里面不知道是不是必须改，还是留原来的值好。"  How to unlock the call?

Thanks!
