I just bought an HTC Desire HD while visiting england.
Everything was fine when i had the orange SIM.
Now, when i put an algerian SIM, the phone lock the network
And when the network is locked, i can't acces to anything in the phone, it ask me for the PIN code.
PS : The problem isn't on the SIM
PS1 : The phone is HTC desire HD a9191
Am just asking if there is a way to unlock this ( free )
