Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The most recent model of the flagship Fenix adventure watch brings a life-saving capability: phone-free messaging and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, plus an optional state-of-the-art microLED display in a limited edition. It is Garmin's top device and engineered to be the only tool needed to venture virtually any location and monitor all your movements.

This positions it as an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class workout, movement and adventure tracking. The full offline maps of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and look excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as tested does have an additional day of watch battery life despite the screen always active, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan tied to your mobile provider, like other wearables. However unlike Apple or Google's satellite-capable products, emergency messaging is not included for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while engaged in jogging, cycling or similar activities – along with SOS orbital SOS messaging.

Location updates and texts over orbital are then billed additionally, with higher-tier plans offering various quotas of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the service.

After you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned replies you can send to expedite communication. Spoken messages and calls work OK, although as with most smartwatches, you’re not going to want to use it for extended conversations as the quality is less than ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts whenever you start an exercise, so they can track your live position on a map. It’s great for following competition performance, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically functioned well, although the real location has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, however it is essential to note that satellite service is restricted to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options offered through the support site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling programs on new 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 adds LTE for messaging, call functionality and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re without signal.

The result is an increasingly impressive adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the service. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, cycling or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital functions need ongoing subscription, restricted Garmin Pay bank compatibility, voice capabilities are sluggish, limited wearable functionality versus competing watches.
