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

The latest version of the flagship Fenix adventure watch includes a potentially lifesaving feature: phone-free communication and SOS alerts using 4G LTE or orbital links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an available advanced microLED screen in a limited edition. It is Garmin's top device and designed to be the only gadget needed to venture almost anywhere and track all your movements.

That positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching 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.

You do receive a lot of features for your money, with best-in-class fitness, activity and adventure tracking. The full offline maps of the globe can automatically direct you back to the path if you get lost without a phone, and appear great on the large, sharp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the screen always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your phone carrier, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, emergency messaging is not included for free.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and voice messaging, calls and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, cycling or comparable pursuits – plus emergency orbital SOS messaging.

Check-ins and messages over orbital are then billed additionally, with higher-tier plans including different quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you just venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and friends.

When you text someone, Garmin sends 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 using typed or spoken messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can use to expedite communication. Voice messages and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can configure to automatically send a URL to selected contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it mostly serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned effectively, although the real location has sometimes been delayed when transitioning in and out of strong LTE coverage.

All of these features are available 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 transmit texts, position updates and emergency SOS.

A guide displays you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital 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 parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services available through the support portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal 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 optional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while running after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it is not reliant on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but still desires to be locatable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Cons: extremely expensive, LTE and orbital functions require monthly payment, restricted Garmin Pay bank compatibility, voice features are slow, limited smartwatch features compared with competing watches.
