Your comment is right on. Yep, I have a SimplySafe home alarm and last year they sent out a letter out to watch for a package to update my alarm system from a 2G to 4G/5G cellular connection (SimplySafe doesn't use hardline telephone connections to their Central Station Alarm Monitoring Center it's ALL CELLULAR). In the shipping box was a small 4"x1-1/2"x1/8 in. circuit board with a new SIM card installed. The instruction said open the Cylindrical Alarm Control 'Tube' slide out the old circuit board and slide in the new board, close up the Alarm Control 'Tube' then power the system back up. Within 2 mins my alarm was updated to the new Cellular system and it's been working perfectly ever since. Yes, it took a whole 2 min. to bring my SimplySafe from the 2G world to the 4G/5G world of today. I called SimplySafe about the upgrade and they told me they know for years 2G would go away and they engineered into their system to quickly update their system BY THE HOMEOWNER, not some tech (or mechanic). SimplySafe is just a small $1Billion company and Hyundai is a $1.93 TRILLION company and Hyundai didn't have the foresight, BULLSHIT. Here's what's true, Hyundai knew by not updating the cellular connection in BlueLink it would force owners to purchase a new car sooner. I am pursuing Hyundai for the fraud they perpetrated and I will keep you up to date on my results.
