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

This most recent model of Garmin's flagship Fenix adventure watch brings a life-saving capability: phone-free messaging and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge mobile tech, along with an available advanced microLED screen in a limited edition. It is the brand's premier device and engineered to be the only gadget required to venture almost anywhere and monitor every activity.

This positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the standard Fenix 8.

Users receive a lot of functionality for your money, with best-in-class workout, activity and adventure monitoring. Its full offline mapping of the world can automatically direct you return to the path if you get lost without a phone, and look great on the large, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite service plan instead of depending on a watch plan linked to your phone carrier, like other smartwatches. But in contrast to Apple or Google's satellite-enabled products, emergency messaging is not included for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out running, biking or similar pursuits – plus SOS satellite SOS alerts.

Location updates and texts over satellite are then charged on top, with higher-tier plans offering different allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you can make and take calls, send texts and generally stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random 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 make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable pre-set responses you can send to expedite communication. Spoken messages and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to automatically send a link to chosen contacts whenever you start an exercise, so they can follow your live position on a map. It’s great for following competition progress, but it primarily acts as a tool for someone you rely on to know your location in case an incident occurs. It has typically worked well, although the actual location has occasionally been delayed when transitioning in and out of strong LTE signal.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that satellite service is limited to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered through the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin offers recycling schemes on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans cost 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 adds LTE for messaging, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without coverage.

Outcome is an increasingly remarkable adventure device for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is very liberating to be outdoors without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone provider so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but still wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

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

Drawbacks: extremely costly, LTE and satellite functions need monthly subscription, limited Garmin Pay financial compatibility, voice features are slow, basic wearable functionality versus Apple/Google/Samsung watches.
