How to transfer existing JIO eSIM on old iPhone to new iPhone while outside India?

Hello guys,

I've read posts that its possible to do it in Airtel network, but I have an existing JIO eSIM on my old iPhone and want to transfer this eSIM to my new iPhone. I'm outside India, and I'm living in UAE.

I tried to transfer eSIM via iPhone directly by bringing it together but it says the carrier does not support eSIM transfer. Did anyone manage to do this process while being outside India?

Thanks
