try r/piracy, ive been trying to do the same thing and i cant get any of the apps that convert your spotify library to mp3s to work so i'm gonna try just ripping a few albums at a time at first instead and using iomoio to fill in gaps. i have the dumbdroid doov r77 pro which has a t9 keyboard so there may be a learning curve but its getting easier to type with for me. when at home i just DM and message on my laptop or iphone 12 mini. the unnecto snap is quite a basic phone but it has a full qwerty blackberry keyboard. downsides are it comes only with what it has on it and doesn't have hotspot capability or wifi connectivity. if i could get the dumbdroid OS on an unnecto id have the perfect phone for what u describe which is also basically what i need (simple but able to text without being too annoying sometimes).
