Older model cell phone (60446)

Has anyone upgraded their phone and have an older one they no longer use? I rarely use a cell but mine is so slow it's almost unusable. Maybe Samsung S8,9,10 or similar Samsung? Don't know much about Iphones but something about the same age as the above Samsungs would be good. Unlocked would be great, or should be able to use TMobile. Close to Romeoville would be nice :) If you have one sitting around let me know, or even if you know a good place to buy used phones of this type, thanks.
