The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Texting

This newest model of Garmin's top-tier Fenix outdoor timepiece includes a life-saving capability: phone-free communication and emergency alerts via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new cellular tech, plus an available advanced microLED display in a special edition. This is the brand's premier device and engineered to be the only tool required to venture virtually anywhere and track every activity.

This makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the regular Fenix 8.

You do get a lot of features for your investment, with industry-leading fitness, movement and outdoor monitoring. Its complete offline mapping of the globe can automatically direct you back to the path if you lose your way absent a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life even with the display always active, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

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

Instead, subscriptions start at £7.99 or equivalent a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can monitor you while engaged in running, cycling or similar activities – plus SOS orbital SOS alerts.

Check-ins and messages over satellite are then charged on top, with more expensive plans including different allowances of satellite use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or voice communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned responses you can send to expedite communication. Voice recordings and calls work OK, although as with most smartwatches, you’re unlikely going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to automatically send a URL to selected contacts whenever you begin an exercise, so they can track your real time position on a map. It’s excellent for following competition progress, but it primarily serves as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally functioned well, though the real location has sometimes been delayed when moving in and out of good LTE signal.

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

A guide shows you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, though it is essential to remember that satellite service is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services available via the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal schemes on new purchases.

Price

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 begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without signal.

Outcome is an even more impressive outdoor tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is very liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the features. At least it is not reliant on your phone provider so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors everything with premier GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and satellite features require monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, limited smartwatch functionality compared with competing watches.
