NikhilKashid You must activate phone with indian sim. Later you can take out the indian sim and put in any other and it will work. If you do a factory reset, you will have to activate the phone again with india sim
//Edit//
Just write to support that you have an Indian version of phone 2. You have to provide where you are currently located and what card you will use to activate the phone. Support Nothing will unlock the phone for you. 🙂
