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

The latest model of Garmin's flagship Fenix outdoor timepiece includes a life-saving capability: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an available state-of-the-art microLED screen in a special edition. It is the brand's top model and engineered to be the only tool required to explore virtually any location and monitor all your movements.

This positions it as an extremely expensive proposition, 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 display – almost twice the price of the standard Fenix 8.

You do receive a significant features for your money, with industry-leading workout, activity and outdoor tracking. Its complete offline mapping of the globe can automatically direct you back to the trail if you get lost without a phone, and appear great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your phone provider, as with other smartwatches. But in contrast to Apple or Google's satellite-capable devices, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in jogging, biking or comparable pursuits – along with emergency satellite SOS messaging.

Location updates and texts via satellite are then billed on top, with more expensive plans offering different allowances of satellite use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the service.

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you can make and take calls, send texts and overall stay connected with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth using typed or voice communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a phone number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned replies you can use to expedite communication. Spoken messages and calls work acceptably, although as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to selected contacts every time you start an exercise, so they can follow your live location on a map. It’s great for monitoring race progress, but it mostly serves as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, although the real position has occasionally lagged when moving in and out of strong LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available through the support 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 components. Garmin offers disposal schemes on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach service to provide the service. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or hiking, but still wants to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Cons: extremely expensive, LTE and orbital features require monthly subscription, limited Garmin Pay bank compatibility, speech features are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
