Hello all!

I bought the Samsung S7 phone in unlocked condition from eBay in US. Then I had to move to India for work related purposes and I was able to use the phone using an Indian sim. The phone developed charging issues and it was not charging. So I had to send it to US where Samsung changed the motherboard. Now, I received the phone which is working but it shows invalid sim if I put any Indian sim. It seems Samsung have restored the phone to original settings which is locked to Sprint network. Samsung tells me to contact Sprint. While Sprint says that they need the account details or confirmation from the person who bought the phone from Sprint. The eBay account from which I got the phone does not exist anymore.

I think I need to unlock the phone so that I can use other sim in India. Could anyone suggest what could be done here?

Thanks!
