How to use sim2's internet while on call with sim1

[vvnsk]

I am using s21fe and I need a workaround to avoid disconnecting internet on sim2 while I was on call on sim1. I have been struggling with this problem. Sometimes i use my phone hotspot for office work and suddenly if I get any call my work gets stopped. 

Is there any way to avoid this issue or if possible can I have any bixby routine to disable sim1 with a single click instead of going all the way into settings and disabling the sim.

Go to settings/ connections/ SIM card manager /Turn on Data switching.

But for this to work I should have data balance on sim1 too

First tell me what you want to ask.

Do you have data balance in Both of your SIM?
Do you have calling available in Both SIM?
Which SIM you use in slot 1 and 2?


Do you want to use internet on SIM 2 while on call from SIM 1?
Then turn data switching. It requires data available in SIM 2.

I am having data balance only in sim2 which is jio but I get all my calls on sim1 which is bsnl

And that is the reason you cannot use data while calling from BSNL. BSNL provide 3G/2G services which doesn't support single channel service(Voice over service).


In simple words, BSNL doesn't support voice over services like VoLTE on 4G and VoNR on 5G.
