Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The most recent model of the top-tier Fenix outdoor watch brings a life-saving feature: phone-free messaging and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, along with an optional advanced microLED screen in a limited edition. This is Garmin's premier model and engineered to be the only gadget required to explore almost any location and monitor all your movements.

This makes it an very pricey proposition, priced from £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 display – almost twice the cost of the regular Fenix 8.

You do get a significant features for your investment, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the world can automatically guide you back to the trail if you lose your way absent a phone, and look excellent on the sizable, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

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

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in running, biking or similar pursuits – along with emergency satellite SOS alerts.

Location updates and texts over satellite are then charged additionally, with higher-tier plans offering different allowances of satellite usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is slow. It has a collection of customisable canned replies you can use to speed things up. Spoken recordings and calls work OK, though as with most smartwatches, you’re not going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the most useful function. You can configure to automatically send a link to selected contacts every time you begin 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 rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, although the real position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are accessible 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 transmit texts, location updates and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is essential to note that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options offered through the customer service portal. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused components. Garmin provides recycling schemes on new purchases.

Price

The 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).

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of coverage.

The result is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the features. Fortunately it isn’t reliant on your phone provider 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, biking or trekking, but nevertheless desires to be locatable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks everything with best-in-class GPS, integrated torch, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.
