I have a Sony Xperia Z1 packed with Android 4.3 Jelly Bean. I'm interested if it's possible to setup my phone to not receive any phone calls or SMS.

I would like to use my Internet connection only, and I don't mean WiFi - my mobile ISP connection from the SIM card.

Is this possible? If so, how?

There is one hack by which you can block your incoming calls.

Go to Settings -> Call settings -> Call forwarding
Now Click on Always forward and enable it to forward the calls to a wrong number.
This will ensure that calls will not come to you and the caller get the tone that call is being forwarded and number is wrong.

You can disable Call forwarding anytime you want.

Hope this will help.

  • I have the same question, but I have to be able to enable and disable phone/sms, quickly and effortlessly, while commuting (so Google Maps keeps working). So digging through settings each time isn't going to dig it. Commented Oct 12, 2018 at 9:35

I don't know about SMS but you can block all incoming calls.

Just go to Settings > Call Settings (under "Device") > Call Blocking and select your preferred settings i.e. Block incoming calls.
