The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

This latest version of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge mobile tech, along with an optional advanced microLED display in a limited edition. It is the brand's top device and engineered to be the single gadget required to explore almost anywhere and monitor every activity.

That makes it an extremely pricey option, priced from £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 variant with microLED display – nearly twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, activity and outdoor monitoring. Its full offline mapping of the world can automatically direct you return to the path if you lose your way without a phone, and look excellent on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as tested boasts an extra day of watch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your phone provider, like other smartwatches. But in contrast to competing satellite-enabled devices, SOS communication is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while out running, biking or comparable activities – plus SOS satellite SOS alerts.

Check-ins and texts over orbital are then billed additionally, with higher-tier subscriptions including different allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you can make and take calls, dispatch texts and generally stay connected with your family and friends.

When 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 message reciprocally via text or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is enough to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned replies you can send to speed things up. Voice messages and calls perform OK, though as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to on its own send a URL to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for following race progress, but it mostly acts as a utility for someone you trust to know your whereabouts in case something happens. It has typically functioned effectively, although the actual location has occasionally lagged when transitioning in and out of strong LTE coverage.

These features are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is essential to remember that orbital coverage is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services offered through the support site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin provides disposal programs on new purchases.

Price

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

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of signal.

The result is an even more remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that capability carries a significant price, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very costly, LTE and orbital functions need monthly subscription, restricted Garmin Pay bank support, voice capabilities are sluggish, limited wearable features versus competing watches.
