I don&#x27;t get how modern phones not having a busy signal forces you to let people contact you. If I really want to disconnect, I just turn stuff off. The only remaining difference is voicemail, but that&#x27;s easily ignored. As for the concern, that&#x27;s not the tool&#x27;s fault, either, just how we use it. People get worried if you don&#x27;t call back in a day because they&#x27;ve become accustomed to you doing so. I&#x27;ve got friends who I will miss a call from and not call back for a few days, and it&#x27;s just fine. Not the phone&#x27;s fault at all. The tool is still controllable by you - so long as there&#x27;s a power switch, its in your control.
