How to block all phone calls, but only allow SMS and networking?

Question

It's kinda disturbing when people keep calling me during work or meetings, but to me it's okay if I receive short messages or Whatsapp message because I can reply them few minutes later in a short break. I'm new Android user and wonder if my phone could do that for me.

Maybe just suppress the ringtone, so you at least know who has tried to call you? — MrWhite, Feb 28 '13 at 08:37

You can use the tried and tested Call Barring method

Go to Settings
Select Call Settings
Look for Call barring
Now select All Incoming
Enter your default PIN (1234)

There, all incoming calls will be blocked. You may still be able to place calls unless you barred that too.

This feature is carrier network dependent and it already exists in the dumbphone era. Still useful though.

I am unable to find call barring option in Nexus 5. Can you please help. I want to block all incoming call. – Ashok Shah May 04 '15 at 21:59
This won't work without proper support from the carrier, as you mentioned. And there are surprisingly many carriers which don't support this. – Display Name Jun 03 '15 at 12:38

(At least in some phones, for example LG G3) there's an option for this:

Settings / Networks / Call / (select Common if this is dual SIM device) / Call reject. You can select Reject all calls in Call reject mode to reject all calls automatically.

This is standard in Android now, should work in all phones. Settings > Call > Call Reject. – Chris Moschini May 16 '16 at 14:23

Try this:

Go to Contact list
Select contact
Open menu, and press the "Block" button (or "Add to blocklist")

I also found Call Guard in the Play Store. Maybe you take a look at it.
