Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The latest iteration of Garmin's top-tier Fenix outdoor watch introduces a potentially lifesaving feature: phone-free communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge mobile technology, plus an available advanced microLED display in a limited edition. It is Garmin's premier model and designed to be the only tool needed to explore almost anywhere and track all your movements.

That positions it as an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the price of the standard Fenix 8.

Users receive a significant features for your money, with best-in-class fitness, movement and adventure tracking. Its full offline maps of the world can automatically guide you return to the trail if you get lost absent a phone, and look excellent on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an extra day of watch battery life despite the display on all the time, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your mobile carrier, like other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not included for no cost.

Rather, plans start at £7.99 or similar a month, which includes limitless LTE text and voice messaging, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while out running, biking or similar activities – plus SOS satellite SOS messaging.

Check-ins and texts over satellite are then charged additionally, with higher-tier subscriptions offering various quotas of orbital use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just venture outside without your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you are able to make and take calls, send texts and overall keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message reciprocally via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to on its own send a URL to chosen contacts whenever you begin an exercise, so they can track your live position on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, although the actual position has sometimes been delayed when moving 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 does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered via the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused components. Garmin offers recycling schemes 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable outdoor tool for those that desire to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is very freeing to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the service. At least it is not reliant on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but still desires to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED display, monitors all activities with premier GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay financial support, speech features are slow, limited wearable features versus competing watches.
