An emergency satellite locator/communication device was once something pretty much reserved for sailers, pilots, or extreme expeditions - if your ship is sinking, your plane is going down, or polar bear is gnawing on your leg, you could press the SOS button and (hopefully) someone could more easily find your remains.
The older style, called a Personal Locator Beacon, or PLB, is designed for emergency use, one-way transmit only. Push the big button, and your lat-long coordinates and an SOS is (hopefully) sent via satellite to the appropriate local search and rescue (SAR) team.
The main problem with this type of device is that the SAR team has no idea what your actual situation is, so they don't know what kind of resources to send. Do you need a helicopter for a life threatening emergency, or did you just break your ankle and can wait a day or so for a rescue team to walk in?
The newer style of satellite communication (satcom) devices offer two-way text capabilities, which is a significant improvement. Satcom devices are now a much more mainstream, every-day-carry item for many people, even on a casual day hike.
As I write this in summer 2022, the most well-known satcom device is the Garmin inReach. I’ve used this device several times, and it works fairly well. However, there are newer competitors on the market, and after testing one called the ZOLEO (yes, all caps), I think it offers some solid benefits over the inReach.
The primary design principle of the ZOLEO is to have the best possible messaging experience, without trying to also be a GPS navigation device. I think they succeeded. For actual navigation, I prefer a phone app like Gaia GPS, a printed map, and a compass. Zoleo was named “Product of the Year” at the Third Annual Outdoor Retailer Innovation Awards in Jan 2021, that's pretty impressive!
Before we get into the specifics of the ZOLEO, let’s look at the bigger picture of satcom devices in general.
There are four primary ways to use a two way satcom device. In order of importance:
1 - Request help in an emergency. You can text back-and-forth with SAR to tell them the exact details about your problem. (Pro tip: this makes SAR teams VERY happy!) SAR not only knows your exact position, but also what resources they need to help you. When you push the SOS button, the device sends your message and coordinates to GEOS (the international emergency response coordination center.) GEOS then notifies your emergency contacts and coordinates with emergency responders in your area.
2 - For a delay, but no emergency, you can text your at-home contact something like: “Everything’s fine, but we’re running late. Do NOT initiate a rescue.” Preventing an unnecessary SAR mission is hugely important, and it's a big benefit of a satcom device that many people may not fully appreciate.
3- Using the “check-in” feature to send a quick text to a few trusted contacts at home, usually saying something like “All good, here's my location.” While this is probably the most common use, let’s remember this is strictly optional. It’s really meant for anxious or concerned people at home, and does not directly benefit the backcountry traveller. (People have been adventuring for thousands of years without making “check-in” calls, so it's a luxury, not a necessity.)
Side note on all satcom devices like this: sending check-in notifications is fine, but don’t let a lack of check-in become the basis for a rescue. If your satcom device breaks, gets lost, dropped in the lake, or runs out of power, and you’re fine, the last thing you want is to trigger an unnecessary “rescue” because you didn’t send your daily check-in. This has happened often! Make it clear to anyone receiving your check-in messages that LACK of communication does NOT mean you have a serious problem.
4 - Treating it pretty much like texting on your phone, and sending any sort of text that doesn’t fall under the previous three categories. Long distance hikers can connect with other hikers. If you’re car camping in the boonies, you could text someone else the coordinates of your campsite so they can meet you, etc. You get the idea.

What separates ZOLEO from the competition? In rough order of importance:
ZOLEO uses whatever available technology is available (and least expensive) to send or receive messages: Wi-Fi, cell tower, or satellite. This allows a seamless thread of conversation if you move from remote backcountry, to cell coverage, to in-town wi-fi. If you're a long distance hiker or like to car camp in remote locations, this is a very handy feature. Messages sent through the ZOLEO over cell or Wi-Fi do not count toward your monthly limit. Plus, messages sent via cell or Wi-Fi are pretty much immediate. With Garmin, you have to bounce back-and-forth between your phone and satcom device to continue the same conversation.
You get a unique email and SMS number (for texts only, not voice calls) with your ZOLEO. Simply share this email or SMS number with anyone, and they can use any device (computer, tablet or phone) to send you a regular text, without you having to initiate a text thread. This is simple, intuitive, and results in fewer missed messages. Compare this to the awkward Garmin inReach system, where you need to first send a text to someone from the device in order to receive a text back from them. This may sound like a minor difference, but it’s actually a pretty big deal.
“Progressive SOS” feature. When an SOS is declared, ZOLEO users receive step-by-step status updates throughout the incident via the ZOLEO app. You’ll know what’s happening at each step, from pressing the SOS button to the time help arrives, as opposed to just pressing the SOS button and then hoping like hell the technology is working. This is the single most important function of the device, so why not make it more intuitive?
Well designed app. For people who will be contacting you more often, they can download the free ZOLEO app. This allows the most characters per message, and, if they’re on your list of preferred contacts, they can receive check-in notifications and (if activated) Location Share+. You and your designated contacts can use one single app for all your communication.
Longer messages. If you and your contacts use the ZOLEO app, messages can have up to 950 characters. Otherwise, emails are limited to 200 characters and SMS messages are limited to 160 characters. Garmin inReach Mini has a 160 characters limit per text.
Here's a screen grab example of the progressive SOS feature.
General ZOLEO features:
Retail price: $200. Weight is a bit over 5 ounces/ 150 grams. Size is very similar to a deck of playing cards.
It doesn’t have a screen. It has four different colored LED lights and some audible alerts, to tell you the basics like battery charging, whether a message was successfully sent or received, etc., so you don't have to look at your phone. The blinking lights are surprisingly intuitive. (I've seen more than one Garmin InReach with a cracked screen, so the screenless ZOLEO could be considered a benefit.)
ZOLEO has three core features: SOS function, preformatted check in message, and two way text messaging. The SOS and pre-formatted check in message work on the device itself, and don’t require your phone. But, you can use the phone app for both of these functions if you prefer. To send and receive texts, you use your phone and connect to ZOLEO via Bluetooth. Yes, you need a functioning phone to send a text message. (You did bring that auxiliary battery and charging cable for your phone, correct? If you're hiking with a partner(s), have them download the app as well so you can both use the device in case one phone is kaput.)
One touch check-in button. Reassure concerned people at home without excessive fiddling with electronics. You can set up to five check-in contacts on the ZOLEO app. Simply press the “check mark” button on the device, and your contacts will get a message like ”I’m OK”, and your latitude longitude coordinates. This will probably be the most common use of the device, and it's nice that it's so easy, literally one touch.
Impressive battery life. Specs say more than 200 hours, even with checking messages every 12 minutes. That’s 20 days if you have it on 10 hours a day, or about eight days if you left it on all the time. The internal battery recharges to full strength in just two hours via micro USB cable. If you're moving in and out of cell coverage, simply leave the device turned on to make sure you catch all your messages. (Having said that, I am a huge fan of always carrying an auxiliary battery and appropriate charging cables, so I’d encourage you to do the same.)
Weather updates. Via satellite. Zoleo uses DarkSky to get weather info. These weather updates count against your total number of messages. I used this several time during my testing. Weather updates came through in just a few minutes, quite impressive.
Location Share+. Added in 2021, this lets you automatically share your location with up to five check-in contacts, on a selectable interval from every 6 minutes to 4 hours. You and your check-in contacts use the ZOLEO app to view the most recently reported location and “breadcrumb” trail on a map. Personally, I don't see this is being very necessary for most hiking and mountaineering, but if you're a pilot or sailor, it could be more important. This feature is an extra $6 a month.
Not just for camping. Keep it in your car for times when you’re driving outside of cell coverage. It's more than an emergency notification device; depending on where you live or recreate, it could be your primary way to connect to the world.
International travel. Heading on a trek to Nepal, Peru, Kilimanjaro, etc.? This could be a great way to stay connected on your trip. Use the device and a single app to stay in touch, without any concern with your phone being compatible in the country you're visiting, changing SIM cards, etc.
Waterproof, rugged, no screen to break, grippy plastic on the outside. Small clip on the top for a carabiner to wear it on the outside of your pack, but I see zero reason to do this. It doesn’t help with satellite connectivity, but it does greatly increase the chance you're going to lose it if you're bushwhacking. I keep it stashed in the top pocket of my pack, which still allows satellite connectivity if you're sending back-and-forth messages with someone during the day. (I see lots of pictures of people wearing satcom devices clipped to the outside of their backpack, and I never understand why.)
Uses the Iridium satellite network, the largest and most reliable. Keep in mind that these satellites move around. If you have a poor connection, wait a few minutes and a new satellite might move into position; in theory, there should be a satellite overhead about every 10 minutes. If you're in a deep canyon and or dense tree cover, satellite connectivity may be affected. Try to have a clear view of the sky. As mentioned just above, there's no need to have this out in the open to work, inside the top of your pack should be fine. Related note, be patient. Messages can often take several minutes to be sent and received. It's never going to be as fast as cell or Wi-Fi.
The ZOLEO app is available in 7 languages (Italian, German, Swedish, Danish, Finnish, Norwegian and French). From the ZOLEO website, spring 2022: “ZOLEO will only accept credit cards with a billing address in the following countries: Canada, United States and its territories, Australia, New Zealand, Denmark, Finland, Norway, Sweden and the United Kingdom. Additional countries will be added over time.”
In addition to the device, you need to choose a subscription plan. There are three levels, depending on how text-happy you are. Data plans start at $20 a month, after three months you can suspend your plan for $4 a month. When you suspend your plan, you keep your dedicated phone number and email address. The amount you pay for the subscription plan is really what the long-term cost of ownership is about, so it's worth taking a close look at this. I won't summarize it here, check the ZOLEO website for details.
So, that's my take on the ZOLEO. It's not a device for everyone. If you hike on mostly frontcountry trails, and you have cell coverage most of the time, any sort of satcom device is probably not needed. But, if you do higher risk activities with off-trail travel in remote areas away from cell coverage (and especially if you lead trips and are responsible for other people) I feel a ZOLEO is well worth the cost, reduced risk, and peace of mind.
Think of it this way: If you use a satcom device just ONCE to help you, a teammate, or another person / group with an emergency situation, isn’t it well worth whatever you spent on it?
Don't just take my word for it. Here are some ZOLEO reviews from solid sources.
