The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The latest model of Garmin's premium Fenix outdoor watch includes a life-saving feature: phone-free messaging and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge mobile technology, plus an optional advanced microLED screen in a limited edition. This is the brand's premier model and engineered to be the single tool needed to venture virtually any location and monitor all your movements.

That positions it as an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model 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 get a lot of features for your money, with industry-leading workout, activity and outdoor monitoring. The complete 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 sizable, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service instead of relying on a watch plan tied to your mobile provider, like other smartwatches. However in contrast to Apple or Google's satellite-enabled products, SOS messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, call functionality and LiveTrack position sharing – so your friends or family can monitor you while out running, cycling or similar pursuits – plus emergency satellite SOS messaging.

Check-ins and texts via orbital are then charged on top, with more expensive subscriptions offering various quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, send texts and generally keep in touch with your family and companions.

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

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can use to expedite communication. Spoken recordings and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful function. You can set it up to automatically send a URL to selected contacts every time you begin an activity, so they can track your real time position on a map. It’s great for following race progress, but it mostly acts as a utility for someone you trust to be aware of your location in case something happens. It has typically functioned effectively, although the actual position has sometimes been delayed when moving in and out of good LTE coverage.

These capabilities are available on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is essential to remember that orbital coverage is limited to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options offered through the support site. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal schemes on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin 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 messaging, call functionality and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable adventure tool for those that desire to be unplugged. 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.

This is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to provide the features. At least it is not reliant on your phone carrier so works with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, cycling or hiking, but nevertheless wants to be locatable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, tracks everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and satellite functions require ongoing payment, limited Garmin Pay financial support, speech capabilities are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
