Unofficial way to make 4G+ on Jio work on OP3/T?

[abhibnl]

I feel this is more of a discussion than a q&a. So, as many fellow Indians will be aware that Reliane Jio has carrier aggregation supported in India. The OP5,5T,6,6T supports it and get 4G+ signal.
The OP3/3T on the other hand, never supported it. There is simply no 4G+ signal on the same spot where OP6 gets full 4G+ bars. I am confident the S820/821 support 2CA, so is it limited by OnePlus and they don't want to introduce software support to support CA on this device? Is there any unofficial guide available to make 4G+ work on Jio network.

My op3 is getting 4G+ on selected locations in Liverpool UK with Vodafone. I know has nothing to do with jio but just as nfo that our phone can get 4G+.

The problem is in india for op3. CA is not supported for any of the bands used here.

Yup, device modem supports it on hardware level. Op has not added support for 4G+ on Indian carriers
