The ZOLEO is a two-way satellite communicator that pairs with your phone and sends text messages and email over the Iridium satellite network from anywhere on earth. What separates it from most competitors is that it automatically routes over cellular or WiFi when either is available and only falls back to satellite when it is not, so you are not paying satellite rates for messages that could have gone over LTE. It has a dedicated SMS number and email address, so contacts reach you directly instead of through an app. Emergency SOS sends your GPS location to a 24/7 monitoring center. Unlimited check-ins are included. It requires an active subscription plan to function. Best fit: solo hikers, backcountry skiers, and anyone whose family worries.

- Unlimited check-in messages are included in every plan tier
Cons

Frequently asked questions
Does it need a subscription?
Yes. The device is inert without an active plan. Plans can be suspended between trips for a small monthly fee rather than cancelled and re-activated.
Does it work without a phone?
Check-ins and SOS work from the device itself. Composing and reading full text messages requires pairing with the ZOLEO app on a phone.
What network does it use?
Iridium, which is the satellite constellation with genuine pole-to-pole global coverage rather than regional coverage.
Can people text you first?
Yes. That is the point of the dedicated SMS number and email address. Contacts message that number normally and it reaches you.
