My primary number is ported to Jio. Calling to Vodafone and Airtel is still an issue. Sometimes several tried are needed. I recently got a call from Jio customer care for network feedback. When I told them about this issue, they agreed that it's still there, Interconnection is still an issue. They are working hard to resolve it is what they said.
Well I am sure nobody has signed up for JioMoney wallet as well while taking Jio SIM but still Jio has opened JioMoney wallet for every customers without their permission.
Jio Wouldn't require your your KYC to open bank account further as they will convert their JioMoney to JioPayment bank
