Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Messaging

The most recent model of the premium Fenix adventure timepiece includes a life-saving capability: phone-free messaging and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge mobile tech, along with an available advanced microLED screen in a limited edition. This is the brand's premier device and designed to be the only tool needed to explore virtually any location and monitor all your movements.

That makes it an very expensive option, 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 variant with microLED screen – almost double the price of the standard Fenix 8.

Users receive a lot of functionality for your money, with industry-leading workout, movement and outdoor tracking. The complete offline mapping of the globe can seamlessly direct you back to the trail if you get lost without a phone, and look excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled products, SOS communication is not provided for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and audio messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, biking or comparable activities – plus emergency satellite SOS alerts.

Check-ins and texts over orbital are then charged on top, with more expensive plans offering different allowances of satellite usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and overall keep in touch with your family and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally using typed or spoken communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of personalizable canned responses you can use to speed things up. Voice recordings and calls perform acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to automatically transmit a link to selected contacts whenever you start an activity, so they can track your real time location on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you trust to be aware of your location in case something happens. It has generally functioned effectively, although the actual position has occasionally lagged when transitioning in and out of good LTE signal.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that satellite coverage is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered through the support site. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin offers disposal schemes on new 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 service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it is not dependent on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or trekking, but still desires to be trackable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, tracks everything with premier GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital features require monthly subscription, limited Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch functionality versus competing watches.
