Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for No-Phone Texting

This most recent model of Garmin's top-tier Fenix adventure watch includes a life-saving feature: no-phone communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular technology, along with an optional advanced microLED screen in a special edition. It is the brand's top device and designed to be the single tool required to venture almost anywhere and track every activity.

That makes it an very pricey proposition, priced from £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 edition with microLED screen – almost twice the cost of the regular Fenix 8.

You do receive a significant features for your investment, with best-in-class workout, movement and outdoor monitoring. The full offline mapping of the world can automatically direct you back to the trail if you lose your way absent a phone, and appear great on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the display always active, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your phone carrier, like other smartwatches. But unlike Apple or Google's satellite-enabled devices, emergency messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, cycling or comparable pursuits – along with SOS orbital SOS alerts.

Location updates and messages over satellite are then billed additionally, with higher-tier plans including various allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can evaluate the service.

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

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via text or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, 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 slow. It has a collection of personalizable canned responses you can send to speed things up. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to selected 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 primarily acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically functioned well, though the real location has sometimes been delayed when moving in and out of good LTE signal.

All of these capabilities are available 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 send texts, position updates and SOS SOS.

A guide displays you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to note that satellite coverage is limited to the US continent, most 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 available via the support site. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled components. Garmin provides disposal schemes on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive outdoor device for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is very freeing to be outdoors without a phone, but that capability carries a significant cost, both in terms of the substantial price 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 network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or hiking, but still desires to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: extremely costly, LTE and satellite functions require monthly subscription, restricted Garmin Pay bank compatibility, voice features are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
