The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Texting

The most recent version of the premium Fenix adventure watch brings a potentially lifesaving feature: no-phone communication and SOS messaging using 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED screen in a limited edition. This is Garmin's top model and engineered to be the single tool required to venture virtually anywhere and monitor every activity.

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

You do receive a significant functionality for your investment, with industry-leading workout, activity and outdoor monitoring. The complete offline maps of the globe can automatically guide you return to the path if you get lost without a phone, and appear excellent on the large, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life even with the display always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan tied to your mobile provider, as with other smartwatches. But unlike competing satellite-enabled products, SOS messaging is not included for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, biking or similar activities – along with emergency satellite SOS messaging.

Location updates and texts via satellite are then billed additionally, with higher-tier subscriptions offering different quotas of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have got it set up, you just venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set responses you can send to expedite communication. Voice recordings and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts whenever you start an exercise, so they can track your real time location on a map. It’s excellent for monitoring competition progress, but it primarily serves as a utility for someone you rely on to know your location in case something happens. It has typically worked effectively, though the actual location has occasionally lagged when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide shows you how to find the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to remember that orbital service is limited to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services offered through the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal programs on new purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription 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 texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re without coverage.

The result is an even more impressive adventure tool for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is very freeing to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the service. At least it isn’t dependent on your phone provider so functions with all make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or trekking, but still wants to be trackable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and orbital functions need ongoing payment, restricted Garmin Pay bank support, speech features are slow, limited smartwatch features compared with competing watches.
