Not able to enable Call barring

[MKShukla]

Why am I not able to enable Call Barring?

What should I do to be able to enable it?

I am using Jio 4G sim in my Galaxy M33.

Why you want it? Did you entered password 0000

[MKShukla]

I want to temporarily block all incoming calls without activating 'Flight mode' so that I may still use internet on my sim.

If you have any other method, then please share it with me.

Password manga kya?

[MKShukla]

Nahi.
Jaise hi call barring mein jaakar 'all incoming calls' par click kiya, call barring rejected message aaya.
Call barring ka koi bhi option activate nahi ho rha hai.

*35*0000# ya *35*1234# dial karo

[MKShukla]

Nahi ho rha☹️
Dono codes try kiye.
Code type karne par kuch nahi hota hai. Jab code type karne ke baad dial par click karo tab invalid mmi code ka message aata hai.
