My main cell phone uses VOIP (Voice Over Internet Protocol) through Fongo. My main transportation at home is the bicycle. After many years now if a phone call needs to be made there are countless public wifi around town that have given me access over the years. Once connected to wifi any voice or text messages are sent to my mobile.
It is nice that my bike riding is not distracted by phone calls and that feeling of being unreachable is kind of nice sometimes. Most of the time, actually. 😎
