Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The newest iteration of Garmin's premium Fenix outdoor timepiece brings a life-saving feature: phone-free communication and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile tech, plus an optional advanced microLED display in a limited edition. This is Garmin's top model and designed to be the single gadget needed to venture almost any location and monitor all your movements.

This makes it an very expensive proposition, starting at £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 display – nearly twice the cost of the regular Fenix 8.

You do get a significant functionality for your money, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the globe can seamlessly guide you back to the trail if you lose your way without a phone, and look excellent on the sizable, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your mobile provider, as with other wearables. But unlike Apple or Google's satellite-enabled products, SOS messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE text and audio messaging, call functionality and LiveTrack location tracking – so your friends or family can monitor you while engaged in running, cycling or similar pursuits – along with SOS satellite SOS alerts.

Check-ins and messages via satellite are then billed additionally, with more expensive plans including different quotas of satellite usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you just 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, send texts and overall keep in touch with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via typed or spoken messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can use to speed things up. Spoken recordings and calls work OK, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to on its own send a URL to selected contacts whenever you start an exercise, so they can follow your live location on a map. It’s great for monitoring race progress, but it primarily acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has typically functioned effectively, though the actual position has occasionally lagged when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, however it is essential to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options available via the support portal. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused components. Garmin offers recycling 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 service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the colossal 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 provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when jogging, cycling or hiking, but nevertheless desires to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.
