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

This most recent version of Garmin's premium Fenix outdoor timepiece brings a potentially lifesaving capability: no-phone communication and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by adding cutting-edge mobile tech, along with an optional advanced microLED display in a limited edition. This is the brand's top model and designed to be the single tool needed to explore almost any location and track every activity.

This makes it an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the regular Fenix 8.

Users get a significant functionality for your money, with best-in-class fitness, movement and outdoor monitoring. The full offline mapping of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and look great on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your mobile provider, like other wearables. But in contrast to Apple or Google's satellite-enabled products, SOS communication is not provided for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in running, biking or similar activities – along with SOS orbital SOS alerts.

Check-ins and messages via orbital are then billed on top, with more expensive subscriptions offering various quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

After you have completed setup, you just head out the door minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, send texts and generally keep in touch with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally via typed or voice communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned replies you can send to expedite communication. Spoken recordings and calls work acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful function. You can set it up to automatically send a URL to selected contacts whenever you begin an exercise, so they can follow your real time location on a map. It’s great for following race performance, but it primarily serves as a tool for someone you rely on to know your location in case something happens. It has typically functioned effectively, although the real location has occasionally been delayed when moving in and out of strong LTE signal.

All of these features are accessible on other Garmin watches if you carry 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 displays you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is important to note that satellite coverage is limited to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services offered via the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused components. Garmin offers 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 additional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re out of signal.

The result is an even more impressive adventure tool for those that want to be unplugged. If you want to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outdoors without a phone, but that capability carries quite a cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the service. At least it is not reliant on your phone provider so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates 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 money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in torch, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital functions require monthly payment, limited Garmin Pay bank compatibility, voice capabilities are slow, limited wearable features versus competing watches.
