I brought my Motorola Droid Pro back from the USA to Switzerland. It has never been actively on any network, as i bought it through Amazon as a "spare phone" on a Verizon network. I never activated the verizon chip. I am now back in Switzerland and when I try and put in my Swiss SIM card and access the network, it asks me for "SIM network unlock PIN". Does anyone know how to unlock it? thanks.
See this thread on XDA-Developers Unlock Motorola Droid Pro:
You simply call Verizon and tell them you're going to spend some extended time in Europe and you want the ability to unlock the phone and change out the SIM card so you can use the phone as a local phone without all the charges, etc. They'll then tell you that you won't have the Verizon guarantee of service, etc., if you remove the SIM card while overseas.
... They gave me a code to use when and if I ever insert a foreign SIM card in the phone. At that time, it will prompt me for the unlock code.
