I still have a smartphone at home as I rely on a couple of things (whatsapp, revolut), but whenever I go outside I just carry this brick and an mp3 player sometimes. It's neat, and thank god I got it for very cheap.

It runs signal! Sometimes. But hey, my closest friends can text me for free on loud places, otherwise they just call me.

Full setup:
>punkt mp02
>dad's old kindle paperwhite
>garmin for when I go out running, casio for normal days
>pocket notebook
>cheapo bluetooth mp3 player
>samsung galaxy buds from ages ago, still work perfectly
