Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest model of Garmin's premium Fenix adventure watch includes a potentially lifesaving capability: phone-free communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding cutting-edge cellular tech, along with an optional state-of-the-art microLED display in a limited edition. This is the brand's premier device and engineered to be the single tool needed to explore virtually anywhere and monitor every activity.

This makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the standard Fenix 8.

Users get a significant functionality for your investment, with best-in-class fitness, activity and outdoor monitoring. Its complete offline mapping of the globe can seamlessly direct you back to the trail if you lose your way absent a phone, and appear excellent on the large, sharp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your phone carrier, like other smartwatches. However unlike competing satellite-enabled devices, emergency communication is not included for no cost.

Rather, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack position sharing – so your contacts or loved ones can monitor you while engaged in running, biking or similar pursuits – along with SOS orbital SOS messaging.

Location updates and messages via satellite are then charged additionally, with higher-tier subscriptions offering different quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and generally stay connected with your family and friends.

When you message someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can send to speed things up. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s great for following race performance, but it mostly acts as a tool for someone you rely on to know your location in case something happens. It has typically worked effectively, though the real location has sometimes been delayed when transitioning in and out of strong LTE signal.

These features are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though it is essential to note that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered through the support site. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused materials. Garmin offers recycling schemes on new purchases.

Price

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re without signal.

The result is an even more remarkable adventure device for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite freeing to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it is not reliant on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, cycling or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.
