Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for No-Phone Messaging

The latest version of the flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone messaging and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new mobile tech, plus an optional advanced microLED screen in a special edition. It is Garmin's premier device and engineered to be the single gadget needed to explore virtually any location and monitor every activity.

That positions it as an extremely pricey option, priced from £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 twice the cost of the regular Fenix 8.

Users get a lot of functionality for your investment, with best-in-class workout, movement and adventure monitoring. Its full offline mapping of the world can automatically direct you return to the trail if you get lost without a phone, and look excellent on the large, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to Apple or Google's satellite-enabled products, emergency messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messages, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while engaged in running, biking or similar activities – along with SOS satellite SOS alerts.

Location updates and messages over satellite are then charged on top, with higher-tier subscriptions including various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to make and take calls, dispatch texts and generally keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable pre-set responses you can send to speed things up. Spoken recordings and calls work acceptably, although as with most smartwatches, you’re not going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts whenever you start an activity, so they can follow your real time position on a map. It’s excellent for following competition progress, but it mostly acts as a utility for someone you trust to know your location in case something happens. It has generally worked well, though the real location has sometimes been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide displays 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 straightforward to use and could be a vital lifeline, though it is important to note that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available through the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin provides disposal schemes on recent 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure tool for those that want to be phone-free. If you want to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin does so without requiring additional gear.

This is very liberating to be outdoors without a phone, but that capability carries quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the features. Fortunately it is not dependent on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and orbital features require ongoing payment, limited Garmin Pay bank compatibility, voice features are sluggish, limited wearable features versus Apple/Google/Samsung watches.
