Thanks for posting.
Where did you see that? I was looking last week if they had mentioned a specific day as my old phone's voice service was still working.
3G Shut-off
A number of Americans will lose cellphone service today as AT&T becomes the first major provider to switch off its 3G communications network. The decision—meant to make way for next-generation 5G networks—will render 3G devices incapable of handling calls, texts, or accessing the internet without Wi-Fi available.
It is unclear how many users will be affected. Apple iPhones older than the iPhone 6 will lose function; a 2019 report suggested at least 30 million users still exclusively used 3G devices. The switch may also affect an unknown number of systems ranging from home security to medical devices. T-Mobile will follow suit in July, with Verizon switching its 3G network off Dec. 31.
