As mobile carriers phase out their 3-G networks to make room for more advanced services like 5-G, customers need to be aware the transition could impact devices other than phones.
Madison College Professor Steve Noll says there are a lot of other devices that may still use older 3-G technology.
They include medical alert necklaces and bracelets, smart watches, older tablets, and crash alert systems in cars.
Some of those have already been turned off.
AT&T has already shut down its 3-G network, and other carriers are set to do so later this year.
Noll says if you’re unsure, check directly with your provider.
