It is fairly easy. I have a fairly dumb feature-phone I almost always leave at home unless I want to be reachable away from home. During work hours I work on a computer connected to the Internet, and can be reached quite reliably via e-mail, or via my employer's office phone.
You do need a mobile phone these days because (in The Netherlands) the government requires SMS authentication for some services, but I don't feel the need to own and carry a smart phone with me all the time.
