Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

This most recent iteration of the flagship Fenix adventure watch introduces a potentially lifesaving capability: no-phone messaging and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's top model and designed to be the single gadget required to explore almost any location and monitor every activity.

This positions it as an extremely pricey proposition, priced from £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 screen – almost twice the price of the standard Fenix 8.

Users get a lot of features for your money, with best-in-class workout, activity and outdoor monitoring. The complete offline mapping of the globe can automatically guide you return to the trail if you get lost absent a phone, and look excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an extra day of watch battery life despite the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your phone provider, like other wearables. However in contrast to competing satellite-capable devices, SOS communication is not included for free.

Instead, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while out running, biking or comparable pursuits – along with SOS orbital SOS alerts.

Location updates and texts over orbital are then charged additionally, with more expensive subscriptions including different quotas of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, 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 phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth via typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable canned responses you can use to expedite communication. Spoken messages and calls work OK, although as with the majority of wearables, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s great for following race performance, but it primarily serves as a utility for someone you rely on to know your location in case something happens. It has typically functioned effectively, although the actual position has sometimes lagged when transitioning in and out of strong LTE signal.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, though it is essential to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options available via the support site. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin offers recycling programs on new purchases.

Cost

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).

Conclusion

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

The result is an increasingly remarkable adventure device for those that desire to be phone-free. If you want to have someone monitor you remotely while running after dark or in the remote areas, the Garmin does so without needing additional gear.

This is quite freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the features. At least it isn’t dependent on your phone carrier so functions with all 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 running, cycling or hiking, but still wants to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors everything 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 waterproofing and 40-metre diving, buttons and touchscreen.

Cons: extremely expensive, LTE and orbital features require monthly payment, limited Garmin Pay financial support, speech features are sluggish, basic wearable functionality compared with competing watches.
