3g shut down, what does it mean for Wyze products

What happens when the 3g networks shut down.

You’ll need a new phone. My wife has an old phone on 3G and I get emails from my provider all the time saying new phone is needed by December 2022.


Well, only when out of the house. It should still work fine on WiFi if they can manage to install the latest Wyze apps.

Absolutely nothing.
Unless you are using a cellular data to WiFi device that is 3G cellular only for your internet for your cameras (not likely).
And as noted by others, if you phone is that old, you will likely need to replace your phone - for pretty much everything (not just Wyze).
