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

This latest model of the flagship Fenix outdoor watch brings a life-saving feature: phone-free communication and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an optional state-of-the-art microLED display in a limited edition. It is Garmin's premier device and engineered to be the single tool needed to explore almost anywhere and monitor 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 edition with microLED display – nearly double the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, movement and outdoor tracking. The full offline maps of the globe can seamlessly guide you return to the path if you lose your way absent a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an additional day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your mobile provider, as with other smartwatches. However unlike competing satellite-capable products, emergency messaging is not provided for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your friends or family can keep an eye on you while engaged in running, cycling or similar pursuits – plus SOS orbital SOS alerts.

Location updates and messages over orbital are then charged additionally, with more expensive subscriptions including various allowances of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

After you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you are able to make and take calls, dispatch texts and generally stay connected with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable canned replies you can send to speed things up. Voice messages and calls perform acceptably, although as with the majority of wearables, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the most useful feature. You can set it up to on its own send a link to selected contacts whenever you start an exercise, so they can track your real time location on a map. It’s great for following race performance, but it mostly acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned well, though the real location has sometimes lagged when moving in and out of strong LTE coverage.

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

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is essential to remember that orbital service is limited to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal schemes 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more impressive adventure device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the features. At least it isn’t dependent on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors all activities with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital functions need monthly subscription, limited Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
