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

This most recent version of Garmin's flagship Fenix adventure watch includes a potentially lifesaving feature: no-phone communication and emergency messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, plus an optional advanced microLED screen in a special edition. This is Garmin's top device and engineered to be the only gadget required to venture virtually anywhere and track all your movements.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the standard Fenix 8.

You do get a significant features for your investment, with industry-leading workout, activity and adventure tracking. The complete offline maps of the world can automatically direct you return to the trail if you get lost without a phone, and appear excellent on the large, sharp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of smartwatch battery life despite the display always active, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital service service rather than relying on a watch plan linked to your mobile provider, like other smartwatches. But unlike competing satellite-capable devices, SOS communication is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable activities – along with SOS satellite SOS alerts.

Check-ins and texts via satellite are then billed additionally, with higher-tier subscriptions including various allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just venture the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you are able to make and take calls, send texts and generally stay connected with your family and companions.

When you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via typed or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable pre-set replies you can send to expedite communication. Voice recordings and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to on its own send a URL to chosen contacts whenever you begin an exercise, so they can track your live location on a map. It’s great for monitoring competition performance, but it primarily acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned effectively, though the actual position has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that satellite coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered via the support site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. Garmin provides disposal programs on recent 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 takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

The result is an even more remarkable adventure tool for those that desire to be unplugged. If you want to have someone monitor you from afar while running after dark or in the remote areas, the Garmin does so without needing additional gear.

It is quite liberating to be outside without a phone, but that functionality comes at quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the service. At least it isn’t dependent on your phone provider so works with all brand of smartphone and carrier.

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

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features need monthly payment, restricted Garmin Pay financial compatibility, speech features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
