++ the future of Microsoft Lumia mobile phones ++

Some WP devices can still work after the 3G shutdown such as the Lumia 950 and Lumia 640 and their XL variants, but I strongly believe that these and their XL variants needed to be made for AT&T (have AT&T IMEIs) for them to work (at least on the AT&T network). The thing is that such phones are still obtainable but a lot of them are used phones. As such, you have to be mindful of that. You would not want to spend money on stuff that is no good. I have a Lumia 950 on Cricket Wireless (that uses AT&T's network), but it is an international unlocked phone (new one) so even if I carry it over to AT&T, it may not work.

You can try getting one that can work with HD calling but be mindful of the price and quality of the phone. I do not need so many apps but I might have to consider what might be needed so that is why I will switch to Android.

Be careful. I have AT&T and I found if I put my sim into another (Samsung) phone just to try it out when I put it back in my Nokia 1520 it wouldn't work. I had to call them to reactivate my sim as they were under the impression my phone didn't have 4g...which it did. Now 2 years later and I finally got tired of losing apps I got an Android phone. If anyone out there is looking for a phone that has the same screen size as the 1520 look at Blu phones. I recently got a Blu G91 Pro and while the phone is slightly less wide I found the screen display was the same as the 1520. And it was only $200. I'm still adjusting to Android/Google but I'm slowly getting around it.

I still use my Lumia 640XL everyday for phone calls and texts. There is no other voice to text system that works as well. I can speak naturally and the text is properly punctuated. Android certainly doesn't do that.

I have an Android 11 phone and it's horrible for speaking texts. I have an Android because of course apps are no longer available or supported on WP.

If they came out with a modern phone I would buy it in a heartbeat. Sadly, that's not going to happen.,

But it's so easy and intuitive to use the old Windows phone.

I'll keep it as long as it works. Fortunately, it's 4G so should be supported for a while yet.

Working flawlessly?

++ in Formula 1 there are teams that do not compete regularly for wins, but have a support role to the championship & Windows 10 mobile devices still can fulfil this support role & in many areas can back up the users' mobile fleet & it's still possible to celebrate the 6th Anniversary of Windows 10 Mobile with well-maintained apps, e.g. : Nitro Nation Drag & Drift & the majority of the Extreme Developers games (e.g. Metal Force or Modern Tanks) ++ many chess apps available, some puzzles, word games, motorbike games (SBK 2016 probably is the most competitive); basketball points games & even table tennis, alpine skiing, billiard or surfing games ++ still plenty of news can be read as well.
