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

The latest version of Garmin's premium Fenix outdoor watch introduces a potentially lifesaving capability: no-phone messaging and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new cellular technology, along with an available state-of-the-art microLED display in a special edition. This is Garmin's top model and designed to be the only gadget required to venture almost any location and track 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 edition with microLED display – nearly twice the cost of the standard Fenix 8.

Users receive a significant features for your money, with best-in-class fitness, activity and outdoor tracking. Its complete offline mapping of the world can automatically guide you back to the path if you lose your way absent a phone, and look great on the large, sharp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as tested does have an extra day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan linked to your phone provider, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in jogging, biking or similar pursuits – plus emergency orbital SOS messaging.

Location updates and messages via orbital are then billed on top, with more expensive subscriptions including different quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

When you message 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 message back and forth via text or spoken messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a mobile number is enough to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable canned responses you can send to speed things up. Voice messages and calls perform acceptably, although as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to selected contacts every time you begin an exercise, so they can follow your live location on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned effectively, although the actual location has occasionally been delayed when transitioning in and out of strong LTE signal.

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

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that orbital service is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services offered through the customer service portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling schemes on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin does so without requiring anything else.

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone carrier so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, cycling or hiking, but nevertheless wants to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, integrated torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely costly, LTE and satellite features need monthly payment, restricted Garmin Pay bank support, voice features are slow, limited wearable features versus competing watches.
