SATPAQ is a cool accessory for your cellphone that will give you the ability to send text messages via Satellite. Check out Rich's story on it here - https://ktla.com/2019/11/08/satpaq-satellite-text-messaging-smartphone-accessory-review/. But it's not cheap, at $250 plus.30 cents per text, sold in $100 packages. As long as you can see the southern sky though, it can keep you connected. Uses Bluetooth and supports both Android and iOS.
