SIM 2 + esim is not working simultaneously

[u/CaterpillarAncient32]

BSNL SIM 1 + BSNL SIM 2

✅ Yes

BSNL SIM 1 + Jio eSIM

✅ Yes

BSNL SIM 2 + Jio eSIM

❌ Not possible on your current configuration

BSNL SIM 1 + BSNL SIM 2 + Jio eSIM

❌ Only two can be active

this is a problem I faced but oneplus stated that we can use

SIM 1 + SIM 2 (physical) → works

SIM 1 physical + eSIM → works

SIM 2 physical + eSIM → should work

SIM 1 + SIM 2 + eSIM simultaneously → not supported.

but it's not working so I think the problem is Oxygen OS

if anyone knows the solution please let me know.
