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

This newest model of Garmin's premium Fenix adventure watch introduces a life-saving capability: no-phone communication and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge mobile technology, plus an available state-of-the-art microLED display in a limited edition. This is Garmin's premier device and engineered to be the only gadget required to explore almost any location and monitor all your movements.

That makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the standard Fenix 8.

Users get a significant functionality for your investment, with industry-leading workout, activity and adventure monitoring. The complete offline maps of the globe can automatically direct you return to the trail if you get lost without a phone, and look excellent on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the display on all the time, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan linked to your mobile provider, like other wearables. But unlike competing satellite-enabled products, emergency communication is not provided for free.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE text and audio messages, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while out running, biking or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and texts via orbital are then billed on top, with higher-tier plans including various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

After you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned replies you can use to speed things up. Voice recordings and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to selected contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, although the actual position has sometimes been delayed when transitioning in and out of strong LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide displays 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 vital lifeline, however it is important to note that satellite coverage is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options offered via the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal programs on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor device for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

This is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the features. At least it isn’t dependent on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but still wants to be trackable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

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

Drawbacks: very expensive, LTE and satellite functions need ongoing payment, limited Garmin Pay bank support, speech features are sluggish, limited wearable features versus competing watches.
