KQ4CMA Yes. The biggest limitation is going to be the very crummy hotspot feature on iOS.
I run a 14 Pro & 12 Pro both on 16.3 and they both regularly drop the hotspot connection. Doesn’t matter if it’s Verizon or AT&T, great signal strength, or all of the battery saving features turned off. While it would be easy to blame my Openspot, I get the same behavior with almost any other device I try to tether to my phones.
It’s enough that I’ve been thinking about getting an Android phone or a dedicated hotspot.
