The Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for Phone-Free Texting

This latest iteration of Garmin's premium Fenix outdoor watch introduces a life-saving capability: no-phone messaging and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile tech, plus an optional advanced microLED screen in a limited edition. This is the brand's top model and engineered to be the only tool required to venture virtually anywhere and track all your movements.

That makes it an very expensive proposition, priced from £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 – almost twice the cost of the standard Fenix 8.

You do receive a significant functionality for your money, with best-in-class workout, activity and adventure tracking. Its complete offline mapping of the world can automatically direct you back to the path if you get lost absent a phone, and appear 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 version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the display always active, enduring a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your phone provider, like other wearables. But unlike Apple or Google's satellite-enabled products, emergency communication is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out jogging, biking or similar activities – along with SOS satellite SOS alerts.

Check-ins and messages over orbital are then charged on top, with higher-tier plans including various quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have completed setup, you simply venture the door without your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, send texts and generally stay connected with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or spoken communications, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a mobile number is enough to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is slow. It has a set of customisable pre-set replies you can use to expedite communication. Spoken messages and calls perform OK, though as with most wearables, you’re not going to want to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a link to chosen contacts whenever you begin an activity, so they can track your live location on a map. It’s excellent for following race progress, but it primarily acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned effectively, though the real location has sometimes lagged when moving in and out of good LTE coverage.

These features are accessible on other Garmin devices 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, position check-ins and SOS SOS.

A on-screen assistance shows you how to find the clear view 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 crucial lifeline, though it is important to note that satellite service is limited to the US continent, 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 offered via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin provides disposal programs on new purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without signal.

The result is an increasingly remarkable adventure device for those that want to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is very liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the features. At least it isn’t dependent on your phone carrier so works with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, biking or hiking, but still desires to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, tracks everything with premier GPS, integrated torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very costly, LTE and satellite functions require monthly payment, limited Garmin Pay bank compatibility, voice features are sluggish, limited wearable functionality versus competing watches.
