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

The most recent version of Garmin's premium Fenix adventure watch introduces a potentially lifesaving feature: phone-free communication and SOS alerts using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an available state-of-the-art microLED screen in a limited edition. It is the brand's premier device and engineered to be the only tool required to explore almost anywhere and track all your movements.

This makes it an extremely 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 variant with microLED display – nearly double the cost of the regular Fenix 8.

You do get a significant features for your investment, with industry-leading fitness, activity and outdoor monitoring. The complete offline mapping of the world can automatically guide you return to the path if you lose your way absent a phone, and look great on the sizable, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of watch battery life despite the display always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan linked to your phone carrier, as with other smartwatches. However unlike competing satellite-enabled products, emergency messaging is not included for free.

Rather, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack location sharing – so your friends or loved ones can keep an eye on you while engaged in running, biking or similar activities – along with emergency satellite SOS alerts.

Check-ins and messages via satellite are then billed on top, with more expensive plans including different quotas of satellite use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can make and take calls, dispatch texts and generally keep in touch with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally via typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a mobile number is enough to register for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can send to expedite communication. Spoken recordings and calls perform acceptably, although as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can set it up to automatically send a URL to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s excellent for following competition performance, but it mostly acts as a tool for someone you trust to be aware of your location in case something happens. It has typically worked effectively, although the real location has sometimes lagged when transitioning in and out of strong LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance shows you how to find the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is essential to note that satellite service is restricted to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options offered through the support site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling programs on new purchases.

Price

The Fenix 8 Pro costs 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

This Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without signal.

The result is an even more impressive outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to enable the features. At least it is not dependent on your phone carrier so functions with any brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks all activities with best-in-class GPS, built-in flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and orbital functions need ongoing payment, limited Garmin Pay bank compatibility, voice features are slow, basic smartwatch features versus competing watches.
