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

This newest iteration of Garmin's premium Fenix adventure watch brings a life-saving feature: no-phone messaging and emergency alerts via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new cellular technology, plus an available advanced microLED display in a special edition. It is Garmin's top device and designed to be the single tool required to venture virtually anywhere and track every activity.

This makes it an very expensive 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 edition with microLED screen – almost twice the price of the standard Fenix 8.

You do get a significant features for your investment, with best-in-class fitness, activity and outdoor tracking. The full offline maps of the world can automatically guide you back to the path if you lose your way without a phone, and look great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the display always active, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription service instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. However unlike competing satellite-enabled devices, SOS communication is not included for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides unlimited LTE text and audio messaging, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, cycling or comparable activities – along with SOS orbital SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive subscriptions including various allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just venture outside without your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you are able to place and receive calls, send texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using text or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to expedite communication. Spoken messages and calls perform OK, although as with most wearables, you’re not going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a URL to chosen contacts every time you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring competition performance, but it primarily acts as a utility for someone you rely on to be aware of your location in case an incident occurs. It has generally worked effectively, though the real location has occasionally been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, 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 remember that orbital service is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services offered via the customer service site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal schemes on new purchases.

Price

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

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without signal.

Outcome is an increasingly impressive adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it isn’t reliant on your phone carrier so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when jogging, biking or hiking, but still desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and satellite messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital functions require monthly subscription, restricted Garmin Pay financial compatibility, speech capabilities are slow, basic wearable features versus competing watches.
