Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The most recent version of Garmin's premium Fenix outdoor watch includes a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding new mobile tech, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's premier device and designed to be the single tool needed to venture virtually any location and track all your movements.

This makes it an extremely expensive proposition, starting at £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 variant with microLED display – nearly twice the price of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class workout, movement and outdoor tracking. The complete offline maps of the world can automatically guide you return to the path if you lose your way without a phone, and look excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your mobile carrier, like other wearables. But in contrast to competing satellite-enabled products, SOS communication is not included for free.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your friends or loved ones can keep an eye on you while out running, biking or similar pursuits – plus SOS orbital SOS alerts.

Location updates and messages over satellite are then charged additionally, with higher-tier plans offering various quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can place and receive calls, send texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using text or spoken messages, and make 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.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable canned replies you can send to speed things up. Voice recordings and calls work OK, though as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to selected contacts every time you start an activity, so they can follow your real time location on a map. It’s excellent for following competition performance, but it mostly acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally worked effectively, although the actual location has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are accessible 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 send texts, position updates and emergency SOS.

A on-screen assistance shows 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 lifeline, however it is essential to remember that orbital coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available through the support site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal programs on new purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without signal.

The result is an increasingly impressive adventure tool for those that desire to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without needing additional gear.

This is quite freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to enable the service. At least it isn’t reliant on your phone provider so works with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but still wants to be locatable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED display, tracks everything with best-in-class GPS, built-in flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and satellite features need ongoing payment, restricted Garmin Pay financial support, speech capabilities are sluggish, basic smartwatch features versus Apple/Google/Samsung watches.
