First: what in the world does that have to do with the claim that you can make a call on satellite???
Second: sending your location with text would be easier. Especially on an iPhone where it automatically does that.
Why in the world are you arguing this? You can’t make a call on a satellite with an iPhone. It’s not possible. And emergency texting via satellite on iPhone automatically sends your location, so you’re doubly wrong??? There’s no need for a phone call at all.
