Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

The latest model of the flagship Fenix adventure timepiece introduces a life-saving capability: phone-free communication and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a special edition. This is the brand's premier device and designed to be the single tool needed to explore virtually anywhere and track all your movements.

That makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, activity and outdoor monitoring. Its complete offline mapping of the globe can seamlessly guide you return to the path if you get lost without a phone, and look great on the large, sharp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of smartwatch battery life despite the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan linked to your mobile provider, like other smartwatches. But in contrast to competing satellite-enabled devices, emergency messaging is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while out running, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Location updates and messages over orbital are then charged additionally, with more expensive subscriptions including various allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and overall stay connected with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone 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 includes a set of personalizable pre-set responses you can use to speed things up. Spoken messages and calls perform OK, though as with most smartwatches, you’re not going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts whenever you start an exercise, so they can track your live position on a map. It’s great for monitoring competition performance, but it mostly acts as a tool for someone you trust to be aware of your location in case something happens. It has typically functioned well, although the actual location has sometimes been delayed when transitioning in and out of good LTE coverage.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows you how to locate 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 important to note that satellite service is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services available via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling programs on new purchases.

Cost

This Fenix 8 Pro is priced 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 fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of coverage.

The result is an even more remarkable outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while running after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or hiking, but still wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: very expensive, LTE and orbital functions require ongoing subscription, restricted Garmin Pay bank support, voice features are sluggish, limited smartwatch features compared with competing watches.
