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

This newest model of the flagship Fenix adventure timepiece brings a life-saving capability: no-phone messaging and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, plus an available state-of-the-art microLED screen in a limited edition. It is the brand's top device and designed to be the only gadget needed to explore almost any location and monitor every activity.

That makes it an very 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 screen – nearly twice the cost of the standard Fenix 8.

You do receive a lot of functionality for your money, with best-in-class workout, activity and outdoor tracking. The full offline maps of the globe can seamlessly direct you back to the path if you get lost absent a phone, and look great on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life even with the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your mobile provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable devices, SOS communication is not included for free.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, calls and LiveTrack position sharing – so your friends or family can monitor you while out running, biking or similar pursuits – along with emergency orbital SOS messaging.

Check-ins and texts over satellite are then billed on top, with higher-tier subscriptions including different allowances of satellite usage, increasing to a £50 a month unlimited 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 link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via text or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. Spoken recordings and calls work OK, though as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can configure to automatically send a URL to selected contacts every time you start an activity, so they can follow your real time location on a map. It’s great for monitoring competition progress, but it primarily acts as a tool for someone you trust to be aware of your whereabouts in case something happens. It has generally functioned well, though the actual position has sometimes been delayed when moving in and out of good LTE coverage.

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

A guide displays you how to find the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, though it is essential to note that satellite service is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options available via the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled components. Garmin provides disposal programs on new 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).

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re without signal.

The result is an increasingly remarkable outdoor device for those that want to be unplugged. 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 anything else.

It is quite liberating to be outdoors without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the service. At least it is not reliant on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, tracks everything with premier GPS, built-in torch, phone and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite functions need ongoing payment, restricted Garmin Pay financial support, voice capabilities are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
