LGRD 3500 cdma phone unlock network lock

I am having a Samsung Nexus SCHi515 with Verizon network( It has a sim slot)
I have taken the phone to India. I thought it could be unlocked and used in some CDMA network( Reliance) here since one of my friend have unlocked LG droid 3,(non-sim model),verizon network. But I have heard from some people that phone with sim slot cannot be unlocked and only the non sim model can be unlocked and registered with the Reliance CDMA network in India.
Is it not possible to unlock the model with sim slot?
Kindly help me out.

A PUK code is a "Pin unlock code" it is used in mobile phones. This code unlocks the SIM card to allow access to your mobile phone. If you enter this code incorrectly several times, then the SIM card will be locked permanently and you will need to purchase another SIM card from your mobile phone provider.
The PUK code is with the documentation that came with your SIM card, if you no longer have the documentation, then you need to contact your phone service provider and ask them for the PUK code.

You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
