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

The latest model of the flagship Fenix adventure watch introduces a potentially lifesaving capability: phone-free communication and emergency alerts via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular technology, along with an available state-of-the-art microLED screen in a limited edition. This is the brand's premier model and engineered to be the single tool needed to explore almost anywhere and monitor every activity.

This positions it as an extremely 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 – nearly twice the cost of the standard Fenix 8.

Users receive a significant functionality for your money, with industry-leading workout, movement and outdoor tracking. Its complete offline maps of the world can seamlessly guide you back to the trail if you lose your way absent a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your phone carrier, like other smartwatches. But unlike Apple or Google's satellite-capable devices, SOS communication is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and voice messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, cycling or similar pursuits – plus SOS orbital SOS messaging.

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

After you have completed setup, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you can make and take calls, send texts and overall keep in touch with your family and companions.

When you text 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 app, you can then message reciprocally via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable canned responses you can use to speed things up. Spoken recordings and calls work acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a link to selected contacts whenever you start an activity, so they can follow your real time location on a map. It’s excellent for following competition progress, but it primarily acts as a tool for someone you trust to know your whereabouts in case something happens. It has typically functioned effectively, though the actual location has occasionally been delayed when moving in and out of strong LTE coverage.

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

A on-screen assistance displays you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is important to remember that orbital coverage is restricted to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered via the support portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides disposal programs on new purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that desire to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the recurring fee of the inReach service to provide the features. At least it is not reliant on your phone carrier so functions with all brand 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 wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: extremely costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay financial compatibility, speech capabilities are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
