The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Messaging

The newest model of Garmin's premium Fenix adventure watch includes a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available advanced microLED screen in a limited edition. This is Garmin's premier device and designed to be the only tool needed to explore almost any location and track every activity.

This positions it as an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the regular Fenix 8.

Users get a significant functionality for your investment, with best-in-class fitness, activity and adventure tracking. Its complete offline mapping of the globe can automatically direct you return to the path if you lose your way absent a phone, and look excellent on the large, sharp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested does have an additional day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your mobile provider, like other smartwatches. But unlike Apple or Google's satellite-enabled products, SOS communication is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, cycling or similar pursuits – along with SOS orbital SOS alerts.

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

Once you have completed setup, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you can make and take calls, send texts and generally keep in touch with your family and companions.

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 message reciprocally via text or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned responses you can use to expedite communication. Voice messages and calls work acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically send a URL to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s great for monitoring race performance, but it primarily serves as a tool for someone you rely on to be aware of your location in case something happens. It has typically worked well, though the real location has occasionally lagged when moving in and out of strong LTE signal.

These features are accessible on other Garmin watches if you carry 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 guide shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is essential to remember that satellite service is limited to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered via the customer service portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

The result is an even more remarkable outdoor device for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin does so without requiring anything else.

This is quite liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to provide the features. At least it is not dependent on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless wants to be locatable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors all activities with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: very expensive, LTE and orbital features need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, basic smartwatch features compared with Apple/Google/Samsung watches.
