Not that the problem isn't a problem, because it is, but: I use the Dexcom G7 (as a type II) and for anyone concerned about this, you can get a receiver - a little device that will show the readings. It's more convenient on the phone (although the phone app FUCKING SUCKS DONKEY BALLS.........), but you don't have to use the phone. With my insurance, it was $50, so that'll vary, but it's an option.
