I still have my first cellphone from about 1990, it is analog, and won’t connect to the system anymore, but makes a nice paperweight.
Still use flip phones, but my all time favorite was the diminutive Nokia 8210. I see that these are available on eBay... can they be configured to operate on a US system?
