The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

The most recent model of the flagship Fenix adventure timepiece introduces a life-saving capability: no-phone messaging and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an available advanced microLED screen in a limited edition. It is the brand's premier device and designed to be the single gadget required to venture almost any location and track all your movements.

That makes it an extremely pricey option, starting at £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 – almost twice the cost of the regular Fenix 8.

Users get a lot of functionality for your investment, with industry-leading fitness, activity and adventure monitoring. Its complete offline mapping of the world can automatically guide you return to the trail if you get lost without a phone, and look great on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan linked to your mobile carrier, as with other wearables. But unlike competing satellite-enabled devices, SOS communication is not included for no cost.

Rather, plans start at £7.99 or similar a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in running, cycling or comparable activities – plus emergency orbital SOS messaging.

Check-ins and texts over orbital are then charged on top, with more expensive plans offering various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the service.

After you have got it set up, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and companions.

Whenever 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 app, you can then message back and forth using typed or voice communications, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable canned replies you can use to speed things up. Voice messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to automatically transmit a link to selected contacts whenever you start an activity, so they can follow your live location on a map. It’s excellent for monitoring race progress, but it mostly serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked well, though the actual position has occasionally been delayed when moving in and out of good LTE signal.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position 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, 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 north.

Environmental Impact

The watch is typically repairable with services offered via the support portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling programs on recent purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable adventure device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the service. At least it isn’t dependent on your phone provider so functions with any make of smartphone and network.

This 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 reachable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay financial support, voice features are slow, limited wearable functionality versus Apple/Google/Samsung watches.
