It’s cheap, but it works well… Samsung Solstice. Was used on AT&T for years until I upgraded to a new phone and new plan. I bet I hadn’t used it for 20 hours of talk time the years I’ve had it.
3G/GSM, touchscreen, older software (no Facebook built-in) and FREE.
Comes with the box, manual, CD, phone, and blue padded rubbery cover. Has been freshly reset to factory defaults.
And did I say FREE?
(I have not researched any software/firmware upgrades for this.)
