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

This newest model of the top-tier Fenix outdoor watch brings a life-saving feature: no-phone messaging and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding cutting-edge cellular tech, along with an available advanced microLED display in a limited edition. It is Garmin's top model and engineered to be the only tool required to explore almost anywhere and monitor all your movements.

That makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the price of the standard Fenix 8.

You do get a lot of features for your money, with industry-leading fitness, activity and adventure tracking. The complete offline mapping of the world can automatically guide you back to the path if you get lost absent a phone, and look excellent on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your mobile provider, like other wearables. But in contrast to competing satellite-enabled products, SOS messaging is not provided for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while out jogging, cycling or similar pursuits – plus emergency orbital SOS alerts.

Location updates and messages over satellite are then charged additionally, with more expensive subscriptions offering various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you can place and receive calls, send texts and overall keep in touch with your relatives and friends.

When you message someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can use to expedite communication. Voice recordings and calls work acceptably, though as with most wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to selected contacts every time you start an exercise, so they can follow your live position on a map. It’s great for monitoring competition performance, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has generally worked well, though the real location has sometimes lagged when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to find 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 safety feature, though it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered via the support site. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling schemes on recent purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription 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 incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of coverage.

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

It is quite freeing to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the service. At least it is not reliant on your phone provider so works with any make of smartphone and carrier.

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

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: very expensive, LTE and satellite functions require monthly subscription, restricted Garmin Pay financial compatibility, voice features are slow, limited wearable functionality versus Apple/Google/Samsung watches.
