I just recently got a Satpaq (SatPaq) unit that connects to your iPhone or Android phone via an app (SpaceLinq) and allow you to send and receive text messages, get weather info, or send SOS with GPS location. What was attractive about this unit, as opposed to Garmin/Inreach Explorer+/mini and others was that it doesn't require a subscription plan (you buy packs of messages) and that you can use the phone you already have. First couple of uses seem encouraging, but wondering if others have tried this one and have thoughts?
