A phone shop managed to palm one off on my FIL around the same time MS threw in the towel. He was using it until last Christmas when we got him a replacement due to it not having LTE and the 3g signal being switched off in the UK last month.
When I say he used it, I mean he could make and receive calls, and could read (but not send) texts. The lack of app support never bothered him because he never needed a smartphone in the first place. We got him a flip phone with physical keyboard and VoLTE. I had to use the WP a bit while dealing with the network to get a new 4g SIM and the UI, while alien, was surprisingly snappy for such an old device.
