Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Texting

The newest version of Garmin's flagship Fenix outdoor watch includes a potentially lifesaving feature: no-phone messaging and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile tech, plus an available advanced microLED screen in a limited edition. This is Garmin's top device and engineered to be the only gadget needed to venture virtually any location and track every activity.

This makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a significant features for your money, with industry-leading workout, activity and adventure monitoring. The complete offline mapping of the world can automatically direct you return to the path if you lose your way without a phone, and look excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of watch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. But in contrast to competing satellite-enabled products, emergency communication is not included for no cost.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE SMS and voice messages, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in jogging, biking or comparable activities – plus SOS satellite SOS alerts.

Location updates and texts via satellite are then billed on top, with more expensive subscriptions offering various allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

Once you have completed setup, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and overall stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally using text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. 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 most useful function. You can configure to on its own send a URL to chosen contacts every time you begin an exercise, so they can track your live position on a map. It’s great for following race progress, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically worked well, although the real location has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities 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, location check-ins and SOS SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is essential to remember that orbital coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with services offered via the support portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal schemes on recent purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re without signal.

The result is an even more impressive outdoor device for those that desire to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

This is very freeing to be outside without a phone, but that functionality comes at a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t dependent on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still wants to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED display, tracks everything with premier GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and orbital functions require monthly payment, limited Garmin Pay bank compatibility, voice features are sluggish, limited smartwatch functionality versus competing watches.
