Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This newest iteration of the premium Fenix adventure watch introduces a life-saving capability: phone-free communication and emergency alerts via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new cellular tech, along with an available advanced microLED screen in a limited edition. This is Garmin's premier model and designed to be the single gadget required to explore almost any location and monitor all your movements.

That makes it an very expensive proposition, starting at £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 screen – almost double the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with best-in-class fitness, movement and adventure monitoring. Its complete offline mapping of the world can seamlessly guide you return to the path if you lose your way absent a phone, and look excellent on the large, crisp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your phone carrier, like other wearables. However in contrast to competing satellite-capable products, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or similar pursuits – along with SOS satellite SOS messaging.

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

Once you have completed setup, you simply head out outside minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and generally stay connected with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via text or voice communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is slow. It has a set of customisable canned responses you can send to speed things up. Spoken messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for monitoring race progress, but it primarily serves as a utility for someone you rely on to be aware of your location in case something happens. It has typically functioned effectively, although the real location has sometimes been delayed when moving in and out of strong LTE coverage.

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 send texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view 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 crucial safety feature, though it is important to remember that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered via the support site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive adventure device for those that desire to be phone-free. If you wish to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone carrier so functions with all brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors everything with premier GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, 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 bank support, speech capabilities are sluggish, limited wearable features versus Apple/Google/Samsung watches.
