The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

This most recent version of Garmin's premium Fenix outdoor timepiece brings a potentially lifesaving capability: phone-free messaging and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile tech, along with an available state-of-the-art microLED screen in a limited edition. This is the brand's premier device and engineered to be the only gadget required to explore virtually anywhere and track every activity.

This positions it as 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 display – almost twice the cost of the regular Fenix 8.

You do get a lot of features for your investment, with best-in-class fitness, activity and outdoor tracking. Its full offline maps of the globe can seamlessly direct you return to the path if you lose your way without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service service instead of depending on a watch plan tied to your mobile provider, as with other smartwatches. However unlike competing satellite-capable products, emergency communication is not provided for free.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and audio messaging, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out running, cycling or similar activities – plus emergency orbital SOS alerts.

Location updates and texts via satellite are then billed on top, with higher-tier subscriptions including different allowances of orbital use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you can make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via typed or spoken communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a set of customisable pre-set replies you can use to expedite communication. Spoken messages and calls work OK, although as with most wearables, you’re not going to want to use it for extended conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to automatically send a link to selected contacts whenever you start an exercise, so they can follow your live 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 an incident occurs. It has generally functioned well, although the actual location has occasionally lagged when transitioning in and out of good LTE signal.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is essential to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options offered through the customer service site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re without signal.

The result is an even more remarkable adventure device for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

This is very freeing to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the features. At least it is not reliant on your phone provider so works with all brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or hiking, but still wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED display, monitors everything with premier GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: extremely costly, LTE and orbital functions require ongoing payment, limited Garmin Pay financial compatibility, speech features are slow, limited wearable features versus competing watches.
