The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Messaging

The latest iteration of the flagship Fenix adventure watch brings a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's premier device and engineered to be the only gadget required to explore almost any location and monitor every activity.

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

Users receive a lot of features for your money, with best-in-class fitness, movement and adventure tracking. Its full offline maps of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and look excellent on the large, sharp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your phone provider, like other smartwatches. But unlike Apple or Google's satellite-enabled devices, emergency messaging is not included for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – plus emergency orbital SOS alerts.

Location updates and messages via orbital are then billed additionally, with higher-tier subscriptions offering different quotas of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

After you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, dispatch 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 message reciprocally via typed or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a phone number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It has a set of personalizable pre-set responses you can send to expedite communication. Spoken messages and calls work OK, although as with most wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a URL to selected contacts every time you start an activity, so they can track your real time position on a map. It’s excellent for monitoring competition progress, but it mostly serves as a utility for someone you trust to be aware of your location in case something happens. It has typically functioned effectively, though the real position has occasionally lagged when moving in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide displays you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is essential to remember that satellite service is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with services offered via the customer service site. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling programs on recent purchases.

Price

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

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly remarkable outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin does so without requiring anything else.

This is very freeing to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the service. At least it is not dependent on your phone carrier so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and contactable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.
