Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Texting

The newest model of Garmin's top-tier Fenix outdoor watch brings a life-saving capability: no-phone messaging and SOS messaging using 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge cellular tech, plus an available state-of-the-art microLED screen in a limited edition. It is Garmin's premier model and designed to be the single gadget needed to explore virtually anywhere and monitor every activity.

This positions it as an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class workout, movement and outdoor monitoring. The full offline maps of the world can seamlessly direct you back to the trail if you get lost absent a phone, and look great on the large, crisp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your phone provider, like other smartwatches. However unlike competing satellite-enabled devices, emergency communication is not provided for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while out running, cycling or similar pursuits – along with emergency orbital SOS alerts.

Location updates and texts via orbital are then charged additionally, with more expensive subscriptions including various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the service.

Once 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 comparable tasks, but you are able to make and take calls, send texts and generally keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can use to speed things up. Voice messages and calls perform OK, though as with the majority of wearables, you’re not going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own transmit a link to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s great for following race performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has typically functioned effectively, though the actual location has sometimes been delayed when moving in and out of good LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to note that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services available through the customer service site. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused components. Garmin provides disposal schemes on recent purchases.

Cost

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).

Verdict

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

Outcome is an even more remarkable adventure tool for those that want to be unplugged. If you wish to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED display, tracks everything with best-in-class GPS, integrated torch, voice and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay financial support, speech capabilities are slow, basic smartwatch features compared with competing watches.
