Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

The latest version of Garmin's top-tier Fenix adventure watch includes a potentially lifesaving capability: no-phone messaging and emergency messaging using 4G LTE or orbital links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an available advanced microLED screen in a limited edition. It is Garmin's premier model and designed to be the only gadget required to explore almost any location and monitor all your movements.

That makes it an extremely expensive proposition, starting at £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 variant with microLED screen – almost twice the cost of the regular Fenix 8.

You do get a lot of features for your investment, with industry-leading workout, activity and adventure monitoring. Its full offline mapping of the world can seamlessly guide you back to the path if you get lost absent a phone, and appear great on the large, sharp and high-luminance display.

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

No-Phone Messaging, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan tied to your phone carrier, as with other wearables. But in contrast to competing satellite-enabled devices, emergency communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE text and audio messages, calls and LiveTrack position sharing – so your friends or family can monitor you while engaged in running, cycling or similar pursuits – along with emergency orbital SOS alerts.

Check-ins and messages via satellite are then billed additionally, with higher-tier plans offering different quotas of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have got it set up, you just head out the door without your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you are able to make and take calls, send texts and generally stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally using text or spoken messages, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of personalizable canned replies you can send to speed things up. Voice messages and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to automatically transmit a URL to chosen contacts every time you start an exercise, so they can follow your real time position on a map. It’s great for following race progress, but it primarily acts as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, although the real location has occasionally lagged when transitioning in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is important to remember that orbital service is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered via the support site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling schemes on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re without signal.

The result is an increasingly impressive adventure tool for those that want to be unplugged. If you want to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very 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 monthly fee of the inReach service to enable the service. At least it isn’t dependent on your phone carrier so works with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but still wants to be locatable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and satellite functions need monthly payment, limited Garmin Pay bank compatibility, voice features are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
