Can a Verizon Apple Iphone 5 be used in India?

My brother will be coming to India from USA. He is planning to gift me an iphone on my bithday. He is deciding to buy a Verizon Apple Iphone. Will it be compatible with Indian carriers like Airtel, Vodafone? I have also read on the internet that these iphones are in contract with the USA carriers which require an unlock code. Will it be compatible with Indian carriers? I contacted Airtel that there sim cards will be compatible with the iphones from the USA too

Not from Verizon… Wrong kind of phone. Get an AT&T or T-Mobile model, and it *should* work.

No you can't
