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

This most recent model of Garmin's top-tier Fenix outdoor watch brings a life-saving feature: no-phone messaging and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding cutting-edge mobile technology, plus an available state-of-the-art microLED display in a special edition. This is the brand's top model and designed to be the only tool required to explore almost anywhere and monitor every activity.

That makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the regular Fenix 8.

Users receive a significant functionality for your money, with best-in-class workout, movement and outdoor tracking. Its full offline maps of the world can automatically guide you back to the trail if you get lost without a phone, and appear great on the sizable, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the display always active, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone carrier, like other wearables. However unlike Apple or Google's satellite-enabled products, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or equivalent a month, which provides unlimited LTE text and audio messages, calls and LiveTrack position sharing – so your friends or family can keep an eye on you while out running, biking or comparable activities – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive subscriptions offering various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

After you have completed setup, you just venture outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you are able to make and take calls, dispatch texts and generally keep in touch with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message back and forth via typed or spoken messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can send to expedite communication. Spoken recordings and calls perform OK, though as with most wearables, you’re not 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 on its own 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 monitoring competition performance, but it mostly serves as a utility for someone you trust to be aware of your whereabouts in case something happens. It has generally worked well, though the real position has sometimes lagged when moving in and out of good LTE coverage.

These capabilities are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is important to remember that orbital coverage is limited to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services available via the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling schemes on recent purchases.

Cost

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 cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that capability comes at quite a price, 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 is not reliant on your phone carrier so works with all make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, cycling or trekking, but still wants to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, monitors all activities with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Drawbacks: very costly, LTE and satellite functions require monthly subscription, limited Garmin Pay bank compatibility, speech capabilities are slow, basic wearable functionality versus competing watches.
