Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This most recent iteration of Garmin's top-tier Fenix outdoor timepiece includes a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or satellite links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge cellular technology, along with an available advanced microLED display in a limited edition. It is Garmin's premier device and designed to be the only tool required to venture almost anywhere and monitor all your movements.

That makes it an extremely pricey proposition, 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 edition with microLED display – nearly twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, movement and outdoor tracking. Its complete offline mapping of the world can seamlessly guide you return to the trail if you lose your way absent a phone, and appear great on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service service rather than depending on a watch plan linked to your mobile provider, as with other smartwatches. However unlike competing satellite-enabled products, emergency messaging is not included for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack location tracking – so your friends or family can monitor you while out running, biking or similar pursuits – plus emergency orbital SOS messaging.

Location updates and texts via satellite are then charged on top, with more expensive subscriptions including various allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you simply venture 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 place and receive calls, send texts and overall stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via text or spoken messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is sufficient to register 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 personalizable canned responses you can send to expedite communication. Spoken messages and calls work acceptably, although as with most wearables, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to automatically send a link to chosen contacts whenever you start an activity, so they can track your real time position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has typically functioned effectively, although the real position has sometimes lagged when moving in and out of strong LTE signal.

All of these features are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide shows 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 easy to use and could be a vital lifeline, though it is important to remember that satellite coverage is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services available through the support portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused components. Garmin offers recycling schemes 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive adventure tool for those that want to be unplugged. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or trekking, but still desires to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital functions require ongoing payment, restricted Garmin Pay bank support, voice capabilities are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
