I'm switching my cell phone carrier to Ting for a $15/month plan (plus taxes and fees) from my $77.66/mo US Cellular plan. I currently have a Samsung Mesmerize that I purchased in either late 2010 or early 2011. It's a subsidized device and wasn't useable with Ting. So, I bought a used Samsung Galaxy II (a step up from my phone, but still pretty "old" as there's a IV out there now) for $265. My savings in monthly fees will have this paid for by the end of the year.
Is there anything I can do with the Mesmerize? Most resale places won't even take it, and from what I've seen, I don't think I could sell it for more than $25, even if anyone was willing to buy it.
