Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Messaging

This latest model of the top-tier Fenix adventure watch includes a life-saving capability: phone-free communication and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED display in a limited edition. This is the brand's premier model and engineered to be the single gadget needed to explore almost anywhere and monitor every activity.

This positions it as an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, movement and adventure monitoring. The complete offline mapping of the globe can automatically direct you back to the path if you lose your way absent a phone, and look great on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your mobile provider, as with other smartwatches. But unlike competing satellite-capable products, SOS communication is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out jogging, biking or similar pursuits – plus SOS satellite SOS alerts.

Check-ins and messages via orbital are then charged additionally, with more expensive plans offering various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have completed setup, you simply venture the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can make and take calls, dispatch texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using typed or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can use to expedite communication. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful feature. You can set it up to on its own send a URL to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s great for following competition progress, but it mostly serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically worked well, though the real position has occasionally lagged when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is important to note that orbital service is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with services available via the support site. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers recycling schemes on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

The result is an even more impressive outdoor tool for those that desire to be phone-free. If you wish to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone carrier so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless wants to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED display, monitors everything with premier GPS, built-in torch, voice and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and satellite functions require ongoing subscription, restricted Garmin Pay bank compatibility, voice features are sluggish, limited smartwatch features versus competing watches.
