The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Messaging

The most recent version of Garmin's flagship Fenix adventure watch includes a life-saving capability: no-phone messaging and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's top model and engineered to be the single gadget needed to venture almost any location and monitor all your movements.

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

Users receive a significant features for your money, with best-in-class fitness, activity and adventure tracking. Its full offline mapping of the world can automatically direct you back to the trail if you lose your way without a phone, and look great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an extra day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your phone provider, like other wearables. However unlike Apple or Google's satellite-capable products, SOS communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messages, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while out running, biking or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and messages via satellite are then charged additionally, with higher-tier subscriptions offering various allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and generally keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using text or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable canned responses you can use to speed things up. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own transmit a URL to selected contacts every time you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you rely on to know your whereabouts in case something happens. It has generally worked effectively, although the real position has sometimes lagged when transitioning in and out of strong LTE coverage.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is essential to note that orbital coverage is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options offered via the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal programs on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service 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 incorporates LTE for texting, calls and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re out of signal.

The result is an even more impressive outdoor device for those that want to be phone-free. If you want to have someone monitor you from afar while running after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is very liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the service. At least it isn’t dependent 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 dislikes being burdened by their phone when running, biking or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and satellite features require monthly payment, restricted Garmin Pay financial support, speech capabilities are slow, basic smartwatch features versus Apple/Google/Samsung watches.
