We live in complex times regarding our relationship to technology, we have already reached a tipping point regarding the geographical, ecological, and social impact of technology, thus looking for alternatives regarding these technologies, both the hardwares that rely on slavey and mining, and the softwares, mostly controled by oligarchies that drive an economy based on spoliation, and have clear right wing political inerests, is not only an interesting personal choince, but a political commitment as well.
However, it is important to understand that these are tools, and sometimes we veer towards a fetishistic aproach toward this topic. Physical media is pretty cool, but having a nice HD with movies you downloaded can be as good as having a collection of dvds, or what seems more concious regularly fixing your smartphone or this wave of buying "dumb" phones. The way you interact and use these technologies is truly what matters.
Why should you use your phone less if your goal is to keep in contact with important people in your life? Using your phone for 3 hours because you have been chatting with friends is different than using it the same time doomscrooling. You can use your messaging app, and block apps or straight up delete apps that you believe are unhealthy for you. Phone time is a quantative number, but you can have a qualitative approach to it.
I apologize if this sounded a bit ranty. I hope you can keep in touch wth your dear friends through many ways, and if the phone is accesiable to all of you, I would say why not? I reccomend using Signal as a messaging app hihi
