The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Texting

The latest model of Garmin's flagship Fenix adventure timepiece introduces a life-saving capability: no-phone communication and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular technology, along with an available state-of-the-art microLED display in a special edition. It is the brand's premier model and engineered to be the single gadget required to explore virtually any location and track every activity.

This makes it an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the standard Fenix 8.

You do receive a significant features for your investment, with industry-leading fitness, activity and adventure monitoring. Its full offline maps of the world can seamlessly guide you return to the trail if you get lost absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life even with the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your phone carrier, like other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, SOS communication is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can keep an eye on you while out jogging, cycling or comparable pursuits – plus SOS orbital SOS alerts.

Location updates and messages via satellite are then billed on top, with more expensive subscriptions offering various quotas of orbital use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

When you text someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using typed or spoken communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a phone number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of customisable pre-set responses you can send to expedite communication. Spoken recordings and calls work OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a link to selected contacts whenever you start an exercise, so they can track your live location on a map. It’s great for monitoring competition performance, but it primarily acts as a tool for someone you trust to be aware of your location in case something happens. It has generally functioned effectively, though the actual location has occasionally lagged when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is essential to remember that satellite service is limited to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services offered via the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal schemes on recent purchases.

Cost

This 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

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re without signal.

The result is an even more remarkable outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to enable the features. At least it is not dependent on your phone provider so works with any make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, biking or trekking, but still desires to be trackable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED display, monitors everything with premier GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital functions need ongoing subscription, restricted Garmin Pay bank compatibility, voice features are slow, basic wearable features compared with Apple/Google/Samsung watches.
