If you search for OpenWRT tutorials on youtube you will find a McFly or something like that name

Could that be OneMarcFifty?

Thanks for your answer. I wasn’t sure what “you have cable” exactly meant, but after seeing BrightCandle’s comment I looked at my ISP contract and it mentions VDSL 50, so I guess I don’t need a separate modem then.

Thanks for your answer! I wasn’t sure about the whole “Cable / FTTH / DSL” issue, but checked my ISP contract and it mentions VDSL 50, so I guess I’m on DSL and don’t need a separate modem. I’m in Europe, by the way (might be relevant to different technologies and devices available), I’ll update the post now to add that.

It can also run LineageOS, iodéOS and /e/ OS at least, so there are a few options for a degoogled OS with this phone.

I would say that being part of the solution is not using their service at all.
