The Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

The latest iteration of Garmin's flagship Fenix outdoor watch brings a life-saving capability: phone-free messaging and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular technology, plus an available advanced microLED screen in a special edition. This is the brand's top model and designed to be the single gadget needed to explore almost anywhere and monitor all your movements.

That positions it as an very expensive proposition, starting at £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 edition with microLED display – nearly double the cost of the regular Fenix 8.

Users receive a lot of features for your investment, with best-in-class workout, activity and adventure monitoring. The complete offline mapping of the globe can seamlessly guide you return to the trail if you get lost absent a phone, and look excellent on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm version found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your mobile provider, like other smartwatches. But unlike competing satellite-enabled devices, SOS messaging is not provided for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE SMS and voice messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – along with SOS satellite SOS alerts.

Check-ins and texts over orbital are then billed additionally, with more expensive plans including various allowances of orbital use, climbing 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 link to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, send texts and generally stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using typed 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 sign up for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can send to speed things up. Voice recordings and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to chosen contacts whenever you start an activity, so they can follow your real time location on a map. It’s great for following competition performance, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned well, although the actual position has occasionally lagged when moving in and out of strong LTE signal.

These capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide shows you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options available via the customer service portal. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin offers recycling programs on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re without coverage.

The result is an even more remarkable outdoor device for those that want to be phone-free. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very liberating to be outdoors without a phone, but that capability 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. Fortunately it isn’t reliant on your phone provider so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down 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 excellent Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: very costly, LTE and orbital functions need monthly payment, restricted Garmin Pay financial compatibility, speech capabilities are slow, basic wearable functionality compared with competing watches.
