How can I unlock my Droid Charge and use it with a sim card in India?
You just have to call VZW Global TS and as long as you meet all of the requirments you will be able to unlock your phone.
The line of service must be active for at least 60 days.
Good Standing is defined as:
The only DROID Charge is a 4G LTE smartphone and isn't global ready. Which means that you can't use it on a GSM network and won't recognize a SIM card other than the Verizon Wireless 4G LTE SIM card. The phone also can't be unlocked.
This January there will be 4g global devices.
The DROID Razr and DROID Razr Maxx are already 4G global ready devices. The update to ICS allowed that function to work.
