I have a locked T-Mobile Desire and wish to use my Orange sim card in it.
I have tested the phone with a T-Mobile sim and this works fine but when I put the Orange sim in I get no signal and the limited service message. I have also tried this with a Vodafone sim card and get the same.
I have a 8 digit unlock code but basically have no where to input it. Can anyone help me with this please?
