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

The most recent model of Garmin's flagship Fenix outdoor watch introduces a life-saving capability: phone-free communication and SOS messaging using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile tech, along with an available state-of-the-art microLED screen in a special edition. This is Garmin's top model and engineered to be the single gadget needed to venture almost any location 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 substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the regular Fenix 8.

Users get a lot of functionality for your money, with best-in-class workout, activity and adventure monitoring. Its full offline maps of the world 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 touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed 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.

Phone-Free Texting, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your mobile provider, as with other smartwatches. But in contrast to Apple or Google's satellite-capable products, emergency messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable activities – plus emergency satellite SOS alerts.

Location updates and texts via satellite are then billed additionally, with higher-tier plans including various quotas of satellite usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to place and receive calls, send texts and overall stay connected with your relatives and friends.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using text or spoken messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned responses you can send to expedite communication. Voice messages and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can configure to on its own send a link to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for following race performance, but it mostly serves as a tool for someone you rely on to know your location in case something happens. It has generally functioned effectively, though the real position has sometimes been delayed when moving in and out of good LTE coverage.

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

A on-screen assistance shows you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services available through the customer service site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides recycling programs on recent purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an even more impressive adventure tool for those that desire to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the remote areas, the Garmin does so without needing anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it is not dependent on your phone provider so functions with all brand of smartphone and carrier.

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

Pros: LTE and satellite messaging, super-bright OLED screen, monitors everything with premier GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and satellite features need ongoing subscription, restricted Garmin Pay bank compatibility, speech capabilities are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
