Which old phones still work for daily use?

I’m really into the 2000s and 2010s. I want to have an older phone. I enjoy the camera quality and the look of it. I kind of enjoy the thought of not having modern social media on my phone, and just happily living between the 2000s and 2010-ish. what phonemodels can still be used in 2025? I enjoy the old Samsungs. Like the Samsung S, and the Samsungs that had a sliding keyboard. Older apples are cool too, like the 3rd gen Apple iPhone, or even the first or second generation. Anyone know what phone I could use for things like photos, texting via phone number, and internet access inbetween these eras? (Doesn’t have to be Apple or Samsung)
