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

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

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an available state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and engineered to be the single tool required to explore virtually anywhere and monitor every activity.

This makes it an very expensive option, priced from £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 double the price of the standard Fenix 8.

You do get a lot of functionality for your investment, with best-in-class workout, activity and adventure monitoring. The full offline mapping of the globe can automatically direct you return to the path if you get lost without a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed boasts an extra day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable products, emergency messaging is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and audio messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while out running, cycling or similar activities – plus emergency orbital SOS alerts.

Location updates and texts via satellite are then charged on top, with higher-tier plans offering various quotas of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and generally stay connected with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It has a collection of customisable pre-set replies you can use to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to on its own send a link 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 tool for someone you trust to be aware of your location in case something happens. It has generally worked effectively, although the actual location has sometimes been delayed when moving in and out of strong LTE coverage.

All of these features are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, however it is important to note that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the support site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin provides recycling programs on recent purchases.

Price

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

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor tool for those that want to be phone-free. If you wish to have someone monitor you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very liberating to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. At least it isn’t dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and standalone voice control, 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.

Cons: very expensive, LTE and orbital functions require ongoing payment, restricted Garmin Pay bank support, voice capabilities are slow, basic wearable functionality versus Apple/Google/Samsung watches.
