internet - Disable calls and SMS and use only mobile data with active SIM card

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?
