The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for Phone-Free Messaging

This newest iteration of Garmin's flagship Fenix outdoor watch introduces a potentially lifesaving capability: no-phone communication and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular technology, along with an optional state-of-the-art microLED display in a limited edition. It is the brand's top device and designed to be the single gadget required to venture virtually any location and monitor every activity.

That positions it as an very pricey option, priced from £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 – nearly twice the cost of the standard Fenix 8.

You do receive a lot of functionality for your money, with industry-leading workout, movement and outdoor monitoring. Its complete offline mapping of the globe can seamlessly guide you return to the trail if you lose your way absent a phone, and appear excellent on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your phone carrier, as with other smartwatches. But in contrast to competing satellite-enabled products, SOS communication is not provided for free.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while out jogging, biking or similar pursuits – along with emergency orbital SOS messaging.

Check-ins and messages over satellite are then billed additionally, with higher-tier plans including various quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via typed or voice messages, and make voice calls. Your recipient 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 functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can use to speed things up. Voice recordings and calls perform OK, though as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to chosen contacts whenever you start an activity, so they can follow your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned effectively, although the actual position has occasionally been delayed when moving in and out of strong LTE signal.

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 orbital kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight 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 lifeline, however it is essential to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused 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 plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re without coverage.

The result is an increasingly impressive adventure device for those that desire to be phone-free. If you want to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to provide the features. Fortunately it isn’t dependent on your phone provider so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, biking or hiking, but still wants to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED screen, tracks everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, 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 monthly subscription, restricted Garmin Pay bank support, voice capabilities are slow, limited wearable features versus competing watches.
