The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Texting

This newest version of Garmin's top-tier Fenix adventure watch introduces a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge mobile tech, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's premier model and engineered to be the only tool required to explore almost anywhere and track all your movements.

That positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the price of the regular Fenix 8.

You do get a lot of features for your money, with best-in-class fitness, movement and outdoor monitoring. Its full offline mapping of the globe can seamlessly guide you return to the path if you get lost absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your mobile provider, like other smartwatches. But unlike competing satellite-capable products, SOS communication is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can monitor you while out jogging, biking or similar activities – plus SOS satellite SOS messaging.

Check-ins and messages over orbital are then billed on top, with higher-tier subscriptions offering different allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you simply head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you can make and take calls, send texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via typed or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is sufficient to register for texts.

Texting on the watch works 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. Spoken recordings and calls work OK, although as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to on its own send a link to chosen contacts whenever you begin an activity, so they can follow your live location on a map. It’s great for monitoring race progress, but it mostly serves as a tool for someone you rely on to be aware of your location in case something happens. It has typically functioned well, although the real location has occasionally lagged when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that orbital service is limited to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with options available through the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on recent 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).

Conclusion

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re without signal.

The result is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outside without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the features. At least it is not dependent on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in torch, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
