Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

This most recent iteration of Garmin's top-tier Fenix adventure timepiece includes a potentially lifesaving feature: phone-free messaging and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an optional advanced microLED screen in a special edition. It is the brand's top model and engineered to be the only gadget required to venture virtually any location and monitor every activity.

This positions it as an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the regular Fenix 8.

You do get a significant features for your investment, with industry-leading workout, movement and adventure tracking. Its full offline maps of the globe can automatically guide you back to the path if you lose your way absent a phone, and appear great on the large, sharp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an additional day of smartwatch battery life despite the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your phone provider, like other wearables. But in contrast to competing satellite-capable devices, emergency communication is not provided for free.

Instead, plans start at £7.99 or equivalent a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – along with SOS satellite SOS alerts.

Check-ins and messages via satellite are then billed additionally, with higher-tier plans including different allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out 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 tasks, but you can place and receive calls, send texts and overall stay connected with your family and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using typed or spoken communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a phone number is enough to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can send to speed things up. Voice messages and calls work acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to selected contacts whenever you begin an exercise, so they can follow your live position on a map. It’s great for monitoring competition progress, but it primarily serves as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically functioned well, although the real position has occasionally lagged when transitioning in and out of strong LTE signal.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance 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 easy to use and could be a crucial lifeline, though it is essential to note that satellite coverage is restricted to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally 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 regular charging. The watch lacks any recycled components. Garmin offers disposal schemes on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors everything with premier GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very costly, LTE and orbital functions require ongoing payment, limited Garmin Pay financial compatibility, voice capabilities are sluggish, basic smartwatch functionality versus competing watches.
