Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Messaging

This most recent iteration of Garmin's premium Fenix adventure timepiece introduces a potentially lifesaving feature: phone-free messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge mobile tech, along with an optional state-of-the-art microLED display in a special edition. It is Garmin's top device and engineered to be the only gadget required to venture virtually anywhere and monitor all your movements.

That positions it as an very expensive 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 variant with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a significant features for your investment, with industry-leading fitness, movement and outdoor tracking. The full offline maps of the globe can seamlessly direct you return to the trail if you lose your way absent a phone, and look great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service service rather than depending on a watch plan tied to your mobile carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, emergency communication is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your friends or family can keep an eye on you while out jogging, cycling or comparable pursuits – plus emergency orbital SOS alerts.

Check-ins and texts via orbital are then charged additionally, with higher-tier subscriptions including various allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you are able to make and take calls, dispatch texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary 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 spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can use to expedite communication. Voice recordings and calls perform OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a link to selected contacts every time you begin an exercise, so they can follow your real time location on a map. It’s excellent for following competition performance, but it primarily acts as a tool for someone you rely on to know your location in case something happens. It has typically functioned effectively, although the real location has sometimes been delayed when moving in and out of strong LTE signal.

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

A guide shows you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy 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 excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options available through the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled materials. Garmin offers disposal programs on new purchases.

Price

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

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

Outcome is an even more impressive outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

This is quite liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to enable the service. Fortunately it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED display, monitors everything with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.
