Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest iteration of Garmin's premium Fenix outdoor timepiece includes a life-saving feature: phone-free messaging and SOS messaging using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge mobile tech, plus an optional state-of-the-art microLED display in a limited edition. It is Garmin's top device and designed to be the single tool needed to explore virtually any location and monitor all your movements.

This positions it as an extremely pricey proposition, starting at £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 – nearly twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your money, with best-in-class workout, movement and outdoor monitoring. The complete offline mapping of the world can seamlessly direct you back to the trail if you lose your way 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 sizes, omitting the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your mobile provider, like other smartwatches. However unlike competing satellite-enabled products, SOS messaging is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can monitor you while out running, biking or comparable activities – along with emergency orbital SOS alerts.

Check-ins and texts over orbital are then billed additionally, with higher-tier subscriptions including different quotas of orbital use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the service.

Once you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally using text or spoken communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set responses you can send to speed things up. Spoken recordings and calls work OK, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can set it up to automatically transmit a URL to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s excellent for following race progress, but it primarily serves as a tool for someone you trust to be aware of your location in case something happens. It has generally functioned well, though the real location has occasionally lagged when transitioning in and out of good LTE coverage.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

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

Sustainability

The watch is generally serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin offers disposal schemes on new 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor tool for those that want to be phone-free. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing 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 features. At least it isn’t reliant on your phone provider so functions with all make of smartphone and carrier.

The 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 trackable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features need ongoing payment, restricted Garmin Pay bank compatibility, speech features are slow, limited smartwatch features compared with competing watches.
