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

This latest iteration of Garmin's top-tier Fenix outdoor timepiece brings a potentially lifesaving capability: phone-free messaging and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an available advanced microLED display in a limited edition. This is Garmin's top model and designed to be the only gadget required to venture almost anywhere and track all your movements.

This makes it an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the standard Fenix 8.

Users get a significant functionality for your money, with best-in-class workout, activity and outdoor tracking. Its full offline mapping of the globe can seamlessly direct you return to the path if you get lost absent a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

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

Instead, plans start at £7.99 or similar a month, which provides unlimited LTE SMS and audio messages, calls and LiveTrack location tracking – so your contacts or loved ones can monitor you while engaged in running, biking or similar activities – plus emergency orbital SOS alerts.

Check-ins and texts via satellite are then billed on top, with more expensive subscriptions offering different quotas of orbital use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you simply head out outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you are able to make and take calls, send texts and generally stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using typed or voice communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a phone number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable pre-set responses you can use to expedite communication. Spoken recordings and calls work acceptably, although as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to selected contacts whenever you begin an exercise, so they can track your real time position on a map. It’s great for following competition progress, but it primarily acts as a utility for someone you trust to know your whereabouts in case something happens. It has generally worked well, though the actual position has sometimes been delayed when moving in and out of good LTE coverage.

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

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

Environmental Impact

The watch is typically repairable with options available via the support portal. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal schemes on new purchases.

Cost

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).

Conclusion

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

The result is an increasingly remarkable adventure device for those that desire to be phone-free. If you want to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the features. At least it isn’t dependent on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, biking or hiking, but still wants to be trackable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED display, tracks everything with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features require ongoing subscription, limited Garmin Pay bank support, voice features are slow, basic wearable features versus Apple/Google/Samsung watches.
