The Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Messaging

The most recent version of the top-tier Fenix adventure timepiece brings a life-saving feature: phone-free messaging and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an optional advanced microLED display in a limited edition. It is the brand's top device and designed to be the only tool needed to venture virtually anywhere and monitor every activity.

That makes it an very pricey proposition, starting at £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 variant with microLED display – nearly twice the cost of the standard Fenix 8.

You do receive a significant features for your investment, with industry-leading fitness, activity and adventure tracking. The full offline maps of the globe can automatically direct you return to the path if you get lost without a phone, and look excellent on the large, sharp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your phone provider, as with other wearables. However in contrast to Apple or Google's satellite-enabled products, emergency messaging is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or family can monitor you while engaged in running, biking or comparable activities – plus emergency orbital SOS alerts.

Location updates and messages via satellite are then charged additionally, with higher-tier plans including different allowances of orbital use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the service.

Once you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you are able to place and receive calls, send texts and generally stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account 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 includes a set of customisable pre-set responses you can use to expedite communication. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to automatically send a link to chosen contacts whenever you begin an exercise, so they can follow your real time position on a map. It’s great for following competition performance, but it mostly serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally functioned effectively, although the actual location has sometimes lagged when transitioning in and out of strong LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is essential to note that satellite coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered through the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin provides recycling programs on recent purchases.

Cost

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but still 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 messaging, high-luminance OLED screen, tracks everything with premier GPS, integrated flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital functions require monthly subscription, limited Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
