The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Messaging

The latest version of Garmin's flagship Fenix adventure watch brings a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular technology, plus an available advanced microLED screen in a limited edition. It is Garmin's top device and designed to be the single gadget needed to venture virtually any location and monitor all your movements.

That makes it an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the regular Fenix 8.

Users receive a significant functionality for your money, with industry-leading fitness, movement and adventure monitoring. The complete offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan instead of depending on a watch plan linked to your mobile carrier, as with other wearables. However unlike competing satellite-capable devices, emergency messaging is not provided for free.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while engaged in jogging, biking or similar activities – plus emergency orbital SOS alerts.

Location updates and texts over satellite are then charged on top, with higher-tier subscriptions including various quotas of satellite use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

After you have got it set up, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, dispatch texts and overall keep in touch with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or spoken messages, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls perform OK, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can configure to on its own send a link to chosen contacts whenever you begin an exercise, so they can track your live position on a map. It’s excellent for following competition performance, but it mostly acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned effectively, though the real location has occasionally lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A guide displays 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 unexpectedly straightforward to use and could be a crucial lifeline, however it is essential to note that orbital coverage is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with services offered through the customer service portal. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch does not contain any reused materials. Garmin provides recycling programs on recent purchases.

Cost

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor tool for those that want to be phone-free. If you want to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

It is very liberating to be outside without a phone, but that capability carries a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the features. At least it is not dependent on your phone carrier so functions with any brand of smartphone and network.

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

Pros: LTE and orbital messaging, high-luminance OLED display, monitors all activities with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

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