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

This latest version of the top-tier Fenix outdoor timepiece introduces a life-saving capability: no-phone communication and SOS alerts using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an available advanced microLED screen in a special edition. It is the brand's premier device and engineered to be the single tool needed to explore almost anywhere and track all your movements.

This positions it as an very expensive option, priced from £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 display – almost twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with industry-leading fitness, movement and outdoor tracking. Its complete offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and look excellent on the sizable, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

The company uses its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to competing satellite-enabled devices, emergency communication is not provided for free.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while engaged in running, cycling or similar pursuits – along with SOS satellite SOS messaging.

Location updates and messages over satellite are then charged additionally, with higher-tier subscriptions including various allowances of orbital usage, 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 the door minus your phone and the watch will link to LTE. You can not use it for streaming music or similar tasks, but you can make and take calls, send texts and overall keep in touch with your family and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using typed or spoken messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It has a set of customisable canned replies you can send to expedite communication. Voice recordings and calls work acceptably, though as with the majority of wearables, you’re unlikely going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to selected contacts whenever you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned effectively, although the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide shows you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is essential to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available via the support portal. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling programs on new 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 plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure 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 out of signal.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without requiring additional gear.

It is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but still desires to be locatable and reachable. For other users, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: extremely costly, LTE and orbital features need ongoing payment, restricted Garmin Pay financial compatibility, voice features are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
