Yes. Phones aren’t the only technology impacted by the sunsetting of these networks. There are e-readers like the Kindle with 3G, portable Internet hotspots, kid’s wearables, alarm systems, personal alarm devices, alcohol monitoring devices and various other Internet-of-things devices that rely on 3G. There are also non-consumer products like systems used by the trucking industry and school bus dispatchers. If you have any kind of home security system or medical alert devices, like the kind that can call for help if you fall, call the company to make sure it is still supported.
