The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Texting

The latest iteration of the top-tier Fenix outdoor watch brings a potentially lifesaving feature: phone-free messaging and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an available advanced microLED display in a limited edition. This is the brand's premier model and designed to be the single gadget needed to explore almost any location and track every activity.

This makes it an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the cost of the regular Fenix 8.

Users receive a lot of features for your investment, with industry-leading workout, activity and outdoor tracking. The full offline mapping of the globe can seamlessly guide you return to the trail if you get lost absent a phone, and look great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan tied to your mobile carrier, as with other wearables. However in contrast to competing satellite-enabled products, emergency messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and voice messaging, calls and LiveTrack position tracking – so your contacts or family can monitor you while out running, cycling or similar pursuits – along with SOS satellite SOS alerts.

Location updates and texts via satellite are then charged on top, with more expensive subscriptions offering various quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you can place and receive calls, send texts and overall keep in touch with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via text or spoken messages, and initiate 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 works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can send to expedite communication. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically send a link to selected contacts whenever you start an activity, so they can track your live position on a map. It’s excellent for following race performance, but it primarily acts as a tool for someone you rely on to be aware of your location in case something happens. It has typically functioned well, although the real position has occasionally been delayed when transitioning in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to note that orbital service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options available via 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 lacks any reused materials. Garmin offers 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 plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

The result is an increasingly remarkable outdoor 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 does so without requiring anything else.

It is very freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial price of the watch and the monthly fee of the inReach service to provide the service. Fortunately it isn’t reliant on your phone carrier so works with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, cycling or hiking, but still wants to be trackable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and orbital features require monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic smartwatch functionality compared with competing watches.
