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

This newest iteration of Garmin's flagship Fenix outdoor timepiece brings a life-saving capability: no-phone communication and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new mobile technology, plus an optional state-of-the-art microLED screen in a limited edition. This is the brand's premier model and engineered to be the single gadget needed to venture almost anywhere and monitor all your movements.

That makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the cost of the regular Fenix 8.

Users get a lot of features for your money, with industry-leading fitness, activity and adventure monitoring. The full offline mapping of the world can seamlessly guide you return to the trail if you lose your way absent a phone, and look great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your mobile provider, like other wearables. But in contrast to Apple or Google's satellite-enabled products, emergency communication is not included for free.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack position sharing – so your friends or family can keep an eye on you while out jogging, biking or comparable pursuits – along with emergency orbital SOS alerts.

Location updates and texts via orbital are then billed on top, with higher-tier subscriptions including different quotas of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can test out the service.

Once 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 playing music or comparable tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally using typed or spoken communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned responses you can use to expedite communication. Spoken messages and calls work OK, though as with the majority of smartwatches, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can set it up to on its own transmit a link to selected contacts whenever you begin an exercise, so they can track your real time location on a map. It’s great for monitoring race progress, but it mostly acts as a tool for someone you rely on to know your whereabouts in case something happens. It has typically functioned well, although the actual position has sometimes been delayed when transitioning in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is important to note that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with services available through the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin provides recycling programs on new purchases.

Cost

This Fenix 8 Pro costs 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 takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is very liberating to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it is not dependent on your phone provider so works with any brand 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 trekking, but nevertheless wants to be locatable and contactable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital functions need monthly subscription, restricted Garmin Pay financial compatibility, voice features are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
