Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Texting

This newest model of Garmin's flagship Fenix outdoor watch brings a potentially lifesaving capability: no-phone messaging and SOS alerts using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular tech, along with an optional state-of-the-art microLED screen in a special edition. This is the brand's premier device and designed to be the only tool needed to explore almost anywhere and monitor 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 model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the standard Fenix 8.

Users get a lot of features for your investment, with best-in-class fitness, activity and outdoor tracking. The complete offline maps of the globe can automatically guide you back to the path if you get lost without a phone, and appear great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable products, SOS communication is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in jogging, biking or similar pursuits – plus SOS satellite SOS alerts.

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

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message back and forth via typed or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, just a phone number is sufficient to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a set of customisable canned responses you can send to expedite communication. Spoken messages and calls perform acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to chosen contacts whenever you start an exercise, so they can follow your real time position on a map. It’s great for following competition performance, but it mostly acts as a tool for someone you rely on to know your location in case something happens. It has typically functioned well, though the real position has occasionally lagged when transitioning in and out of strong LTE signal.

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 transmit texts, position updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is essential to remember that orbital coverage is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered through the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of signal.

The result is an increasingly impressive outdoor device for those that desire to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite freeing to be outside without a phone, but that capability carries a significant price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it is not reliant on your phone carrier so works with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors all activities with premier GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely expensive, LTE and satellite features require ongoing payment, restricted Garmin Pay financial compatibility, voice features are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
