The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Messaging

This newest model of the flagship Fenix adventure watch includes a life-saving feature: phone-free messaging and emergency messaging via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile technology, plus an available state-of-the-art microLED display in a special edition. It is Garmin's top device and engineered to be the only tool required to explore virtually any location and track every activity.

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

Users receive a significant features for your investment, with best-in-class fitness, activity and adventure monitoring. Its complete offline mapping of the globe can seamlessly guide you back to the path if you get lost without a phone, and look excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen always active, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital service service instead of relying on a watch plan tied to your mobile provider, like other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not included for free.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, biking or comparable pursuits – along with SOS orbital SOS alerts.

Location updates and texts via satellite are then charged on top, with more expensive plans offering various allowances of orbital use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally using text or spoken communications, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, just a phone number is sufficient to sign up 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 responses you can send to speed things up. Spoken messages and calls perform OK, though as with most smartwatches, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to automatically send a URL to chosen contacts every time you start an exercise, so they can follow your real time location on a map. It’s excellent for monitoring competition progress, but it primarily serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned effectively, though the real location has sometimes lagged when transitioning in and out of strong LTE coverage.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to note that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services available via the customer service site. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch lacks any recycled materials. Garmin provides recycling schemes 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

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re without signal.

The result is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that functionality comes at a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. At least it is not reliant on your phone carrier so functions with any brand 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 trekking, but still wants to be trackable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with premier GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and satellite functions require monthly subscription, restricted Garmin Pay financial support, speech features are slow, basic wearable functionality versus competing watches.
