Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Messaging

The latest version of Garmin's flagship Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an optional advanced microLED screen in a special edition. This is Garmin's premier device and designed to be the single gadget needed to explore virtually anywhere and track every activity.

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

Users get a lot of features for your investment, with industry-leading workout, activity and adventure tracking. Its full offline mapping of the world can automatically guide you back to the path if you lose your way without a phone, and appear great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have an extra day of watch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your phone carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, emergency communication is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – plus emergency orbital SOS messaging.

Location updates and texts via orbital are then billed on top, with higher-tier plans offering different allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you can make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message 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 app, you can then message back and forth using typed or voice messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to chosen contacts every time you start an activity, so they can track your real time location on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you rely on to know your location in case something happens. It has typically functioned effectively, although the actual position has sometimes been delayed when transitioning in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position 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 communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with services offered through the customer service 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 programs on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of signal.

The result is an even more impressive adventure tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it isn’t reliant on your phone carrier so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, built-in torch, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions require ongoing subscription, limited Garmin Pay bank support, speech capabilities are slow, basic wearable features versus Apple/Google/Samsung watches.
