Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Messaging

The newest model of the premium Fenix adventure timepiece includes a life-saving capability: no-phone communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, plus an optional advanced microLED display in a limited edition. This is Garmin's premier device and engineered to be the single tool needed to venture almost anywhere and track all your movements.

That makes it an extremely pricey option, priced from £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 display – almost twice the price of the regular Fenix 8.

Users get a lot of features for your investment, with industry-leading fitness, movement and adventure monitoring. Its complete offline mapping of the globe can automatically guide you return to the trail if you lose your way without a phone, and look excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable products, emergency messaging is not provided for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while engaged in jogging, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with higher-tier subscriptions including various quotas of orbital use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just venture the door without your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, dispatch texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a set of customisable pre-set responses you can send to expedite communication. Spoken messages and calls work acceptably, though as with most smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to selected contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for following competition performance, but it primarily acts as a utility for someone you trust to know your whereabouts in case something happens. It has generally worked effectively, although the real location has sometimes been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is essential to note that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with services available through the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal programs on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive adventure device 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 requiring additional gear.

It is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. At least it is not reliant on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but still desires to be trackable and contactable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely costly, LTE and orbital features require ongoing subscription, limited Garmin Pay bank compatibility, voice capabilities are sluggish, basic smartwatch functionality compared with Apple/Google/Samsung watches.
