I can't find much current information on which bands Vodafone India supports but if the Motion variant you buy matches the bands that their Keyone does I assume it should work if they allow devices not purchased from them.

Keep in mind though, it probably won't be dual sim. I don't believe any dual sim versions of the Motion have released yet.
I don't know if there will be any problems or delays with updates (I assume that depends on which carrier the device is from), hopefully someone else can answer that.
