Day 734 – Fixing my new phone

Or: How to enable WiFi Calling on the POCO F3. Solved.
tl;dr? – scroll to the bottom of this post.


The cell phone signal is awful here Chez 6000… so I wanted (needed?) to get a phone which supported WiFi Calling, so that I could hook onto the (very good) internet here to make calls.

The Poco F3 does have WiFi Calling, but could I find a way of getting it to work?
No, I couldn’t.

Pages of online instruction booklets, forums, subreddits and Youtube videos were no help. My cellular provider was no help. With the evidence of WiFi Calling being available on the Poco F3 right in front of him, the guy even told me that the Poco F3 probably didn’t have it.
He opened a support request ticket. I have never heard back from them.
Which cellular provider was this? It doesn’t matter: they’re all equally useless.

But then I found this video:

Which told me a lot of the same stuff that I had seen before, but added an extra step.

Suffice to say, my WiFi Calling is now enabled. What a relief.

So, you can watch the video if you want (and it’s brilliantly and clearly explained), but if it’s a case of tl;dw, and for all the search engines out there:
