The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

The latest iteration of the premium Fenix adventure timepiece includes a life-saving capability: no-phone messaging and emergency messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding cutting-edge mobile technology, along with an available advanced microLED screen in a special edition. This is Garmin's premier device and designed to be the single tool needed to explore almost anywhere and track all your movements.

This makes it an extremely pricey proposition, priced from £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 – nearly double the price of the standard Fenix 8.

You do get a lot of features for your money, with best-in-class workout, movement and adventure monitoring. Its full offline mapping of the globe can seamlessly direct you back to the path if you lose your way without a phone, and appear great on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service service rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. But in contrast to Apple or Google's satellite-capable devices, emergency messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while out running, cycling or comparable pursuits – plus emergency orbital SOS messaging.

Check-ins and texts via orbital are then charged additionally, with higher-tier plans offering different allowances of satellite use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you simply head out the door without your phone and the watch will link to LTE. You can not use it for streaming music or similar tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your family and friends.

When you text someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via typed or spoken messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile 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 personalizable canned replies you can send to speed things up. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to on its own send a URL to chosen contacts whenever you begin an activity, so they can track your real time location on a map. It’s great for following competition progress, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally worked well, though the real position has occasionally lagged when moving in and out of strong LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide shows 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, though it is essential to note that orbital service is restricted to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

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 capacity after two years of regular charging. The watch lacks any reused materials. Garmin provides disposal 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

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re without coverage.

The result is an even more impressive outdoor device for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that capability carries quite a 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 isn’t reliant on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless desires to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and satellite features need ongoing payment, limited Garmin Pay financial support, speech features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
