The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

This most recent iteration of the top-tier Fenix adventure timepiece includes a potentially lifesaving feature: phone-free communication and emergency alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by adding cutting-edge mobile technology, along with an available state-of-the-art microLED display in a limited edition. This is the brand's premier device and engineered to be the only tool required to explore almost any location and track all your movements.

This positions it as an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the price of the standard Fenix 8.

You do receive a significant functionality for your investment, with best-in-class workout, activity and outdoor monitoring. Its full offline mapping of the world can seamlessly guide you return to the trail if you lose your way absent a phone, and look excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an extra day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your mobile carrier, like other smartwatches. But unlike competing satellite-capable devices, SOS messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while out jogging, cycling or similar activities – along with emergency satellite SOS messaging.

Location updates and texts via satellite are then billed on top, with more expensive plans including various quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and generally keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using text or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is enough to register for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It has a set of personalizable pre-set responses you can use to expedite communication. Spoken messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for monitoring competition progress, but it mostly serves as a utility for someone you rely on to know your location in case an incident occurs. It has typically worked effectively, though the real position has occasionally lagged 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 areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, though it is essential to note that satellite coverage is restricted to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with services offered through the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling programs on new 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 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 adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without signal.

Outcome is an increasingly impressive adventure tool for those that want to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite liberating to be outside without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to enable the service. At least it is not dependent on your phone provider so works with all make 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 trekking, but still wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital features need ongoing payment, restricted Garmin Pay bank compatibility, voice features are slow, basic wearable features compared with competing watches.
