The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

This latest version of Garmin's top-tier Fenix outdoor timepiece introduces a life-saving capability: phone-free messaging and SOS alerts using 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile technology, plus an optional advanced microLED display in a limited edition. This is Garmin's top device and designed to be the only tool required to explore almost any location and monitor all your movements.

That positions it as an extremely 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 edition with microLED display – almost twice the price of the regular Fenix 8.

You do receive a significant functionality for your money, with industry-leading fitness, activity and outdoor monitoring. The complete offline mapping of the globe can seamlessly direct you return to the path if you get lost without a phone, and appear excellent on the sizable, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable devices, SOS communication is not provided for no cost.

Rather, subscriptions start at £7.99 or similar a month, which provides unlimited LTE text and voice messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while out running, cycling or similar pursuits – plus SOS orbital SOS messaging.

Location updates and messages over satellite are then charged on top, with higher-tier subscriptions offering various allowances of satellite use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you simply head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

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

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can send to speed things up. Voice messages and calls work acceptably, though as with the majority of wearables, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts every time you start an activity, so they can follow your real time location on a map. It’s great for following competition performance, but it mostly acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has generally worked well, although the actual location has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of 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 send texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to remember that satellite service is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch lacks any recycled materials. Garmin provides recycling programs on new purchases.

Price

This Fenix 8 Pro is priced 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 takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re without signal.

The result is an increasingly impressive adventure tool for those that desire to be unplugged. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

This is very freeing to be outside without a phone, but that capability comes at a significant cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or trekking, but still wants to be locatable and reachable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite messaging, super-bright OLED display, tracks all activities with premier GPS, integrated flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: very expensive, LTE and orbital features need monthly subscription, restricted Garmin Pay bank support, voice capabilities are sluggish, basic wearable features versus competing watches.
