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

The latest version of Garmin's top-tier Fenix adventure timepiece introduces a potentially lifesaving capability: phone-free communication and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge cellular tech, along with an optional state-of-the-art microLED display in a limited edition. This is the brand's premier device and designed to be the only gadget required to explore almost anywhere and monitor all your movements.

That makes it an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the cost of the standard Fenix 8.

You do get a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. Its full offline mapping of the world can seamlessly direct you back to the trail if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright display.

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

No-Phone Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan linked to your mobile carrier, like other smartwatches. But unlike competing satellite-enabled devices, emergency messaging is not provided for free.

Rather, plans begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack position sharing – so your friends or family can keep an eye on you while out jogging, biking or comparable pursuits – plus SOS satellite SOS alerts.

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

After you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you are able to make and take calls, dispatch texts and overall keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using text or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned responses you can send to expedite communication. Voice messages and calls work OK, although as with the majority of wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own send a URL to chosen contacts every time you begin an activity, so they can follow your live location on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically worked well, although the actual position has occasionally lagged when transitioning in and out of good LTE signal.

These features 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 send texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options offered through the customer service portal. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling schemes 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 service plans cost 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, calls and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that want to be unplugged. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without requiring additional gear.

It is very liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it is not reliant on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but still desires to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks everything with premier GPS, built-in torch, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: extremely expensive, LTE and satellite functions require ongoing payment, restricted Garmin Pay bank compatibility, voice capabilities are slow, basic wearable features compared with Apple/Google/Samsung watches.
