Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Messaging

The latest version of Garmin's flagship Fenix adventure watch includes a potentially lifesaving feature: no-phone messaging and SOS messaging using 4G LTE or orbital links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an available state-of-the-art microLED display in a special edition. This is Garmin's premier device and designed to be the single tool required to explore virtually any location and monitor all your movements.

This positions it as an extremely expensive proposition, 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 variant with microLED screen – nearly twice the cost of the standard Fenix 8.

Users get a significant features for your investment, with best-in-class workout, movement and adventure monitoring. Its complete offline mapping of the globe can automatically direct you back to the path if you lose your way without a phone, and appear great on the large, crisp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an additional day of watch battery life even with the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your phone provider, like other smartwatches. But in contrast to competing satellite-capable products, SOS communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, biking or comparable activities – along with SOS orbital SOS messaging.

Check-ins and texts via satellite are then billed additionally, with higher-tier plans including various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the service.

After you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls perform OK, though as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a URL to selected contacts every time you begin an exercise, so they can follow your live location on a map. It’s great for following competition performance, but it primarily serves as a utility for someone you rely on to know your location in case an incident occurs. It has typically worked well, though the real position has occasionally been delayed when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is important to remember that orbital service is restricted to the US mainland, 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 available through the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal programs on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable 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 requiring additional gear.

It is very freeing to be outdoors without a phone, but that capability carries quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking 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 orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: very expensive, LTE and satellite functions need ongoing subscription, limited Garmin Pay bank support, voice features are slow, limited wearable features compared with competing watches.
