how to do voice call through SIM2

[dhongdhong]

I have dual sim.

I have already set SIM1 as default master SIM and data connection provider.

Now I want to do voice calls only through slave SIM2. How do I do ?


right now , whenever I'm dialing calls are going through SIM1 ....

I want to route my calls through SIM2. Please guide.
