I used Nokia 3390s for many years until just about a year ago. Best cell phone ever, in my opinion.
For one thing, the monochrome screen is "always on" and screen savers (found on all color screens) drive me insane.
They can be bought cheap on ebay and a battery charge lasts nearly a week if you use it lightly.
Plus they use real earplugs that work without any glitches. And they text.
