Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

The latest model of the top-tier Fenix adventure timepiece brings a life-saving capability: phone-free messaging and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular technology, along with an optional advanced microLED screen in a limited edition. This is the brand's premier device and designed to be the only gadget needed to venture virtually any location and track all your movements.

That makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, activity and adventure monitoring. The full offline maps of the globe can automatically guide you return to the path if you lose your way without a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed 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.

Phone-Free Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your phone carrier, as with other smartwatches. However unlike Apple or Google's satellite-enabled devices, SOS communication is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE text and voice messages, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while out running, cycling or similar pursuits – along with SOS satellite SOS messaging.

Check-ins and texts via satellite are then billed on top, with higher-tier plans including various quotas of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you are able to place and receive calls, send texts and generally keep in touch with your family and companions.

When you text someone, Garmin dispatches 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 message back and forth using typed or spoken messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It has a collection of customisable canned replies you can use to speed things up. Voice recordings and calls work acceptably, although as with most wearables, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to on its own send a URL to chosen contacts whenever you start an exercise, so they can track your live position on a map. It’s excellent for following race performance, but it primarily acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned effectively, though the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is essential to note that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered through the customer service site. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin offers recycling programs 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor device for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it isn’t dependent on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, cycling or hiking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and satellite functions require ongoing payment, limited Garmin Pay financial compatibility, speech capabilities are slow, basic wearable functionality compared with competing watches.
