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

This latest model of Garmin's flagship Fenix outdoor watch introduces a life-saving capability: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge mobile tech, plus an optional state-of-the-art microLED screen in a special edition. It is the brand's premier model and designed to be the only tool needed to venture almost any location and monitor every activity.

This makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the standard Fenix 8.

You do get a lot of functionality for your money, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the globe can seamlessly guide you back to the trail if you lose your way without a phone, and look excellent on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your phone provider, like other smartwatches. However unlike Apple or Google's satellite-capable devices, emergency communication is not included for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and voice messages, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while engaged in jogging, biking or comparable activities – plus SOS satellite SOS alerts.

Check-ins and texts over orbital are then charged on top, with higher-tier plans offering various quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, send texts and generally keep in touch with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned replies you can use to speed things up. Spoken recordings and calls work acceptably, though as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can configure to on its own send a URL to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for following competition performance, but it primarily acts as a tool for someone you trust to know your location in case an incident occurs. It has generally functioned well, although the actual position has sometimes been delayed when transitioning in and out of strong 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 satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A on-screen assistance shows you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to remember that satellite 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.

Environmental Impact

The watch is generally repairable with services offered via the support site. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling schemes on recent purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional 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 – along with orbital messaging, location update and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure device for those that want to be unplugged. If you wish to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is quite liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the service. At least it isn’t dependent on your phone provider so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, integrated torch, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital features require ongoing payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic wearable functionality compared with competing watches.
