The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Messaging

The latest iteration of the top-tier Fenix adventure watch brings a life-saving capability: phone-free messaging and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new cellular technology, plus an available advanced microLED screen in a limited edition. This is the brand's premier device and engineered to be the only tool required to explore virtually anywhere and monitor all your movements.

That makes it an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the regular Fenix 8.

You do receive a significant features for your investment, with best-in-class fitness, activity and adventure tracking. Its full offline maps of the globe can automatically guide you back to the trail if you get lost absent a phone, and appear great on the large, sharp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the display always active, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your mobile carrier, like other smartwatches. But unlike competing satellite-enabled products, SOS communication is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out running, biking or comparable activities – plus emergency satellite SOS messaging.

Check-ins and messages over satellite are then charged on top, with more expensive subscriptions offering various quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the service.

After you have completed setup, you just head out outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, send texts and generally keep in touch with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using text or spoken messages, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable canned replies you can use to expedite communication. Voice recordings and calls perform acceptably, although as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to selected contacts whenever you start an activity, so they can track your live position on a map. It’s great for following race progress, but it mostly acts as a utility for someone you rely on to know your location in case something happens. It has generally functioned effectively, though the actual position has sometimes been delayed when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A guide displays you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is important to note that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with options available through the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal programs on recent purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive adventure device for those that want to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the remote areas, the Garmin does so without needing anything else.

This is very freeing to be outdoors without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach service to provide the features. At least it is not dependent on your phone carrier so works with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be trackable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, integrated torch, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and orbital functions need ongoing subscription, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, basic smartwatch functionality compared with Apple/Google/Samsung watches.
