I own a MP01 that replaced a Nokia 105 that got lost in the Berghain after 12 years of service. I regret buying the Punkt. It costs more than double than the Nokia and is worse in almost every dimension. It is all form over function, with various obvious UX issues. I would not buy from this company again.
I'm waiting for the Punkt to die one day before I buy a new one, don't wanna create unnecessary waste. In spite of its flaws, it is rather robust so it may take a while haha.
There is a 4G edition of the Nokia 105 which would be my next option. But I'm thinking maybe if I move to a 4G phone I'd like it to have the ability to create a wifi hotspot, which none of the cheap Nokias can.
But I dunno, I'm slowly kind of getting tired of the burner phone life... It's just getting harder and harder. I spent three months in the US this summer and it was impossible without one there, even the door of this workshop I was visiting needed a fucking app to open the door, so I did buy the cheapest Samsung (my first ever smartphone). I'm now back in Europe and using the burner phone again, I keep the smartphone for the bank app and what not. But... maybe when this new GrapheneOS device comes out this year (they promised a new non-google device with official OEM support) I may bite the bullet... Or maybe one of those ink-display devices...
