The Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Texting

This newest version of Garmin's premium Fenix adventure timepiece includes a life-saving feature: no-phone messaging and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding new mobile tech, plus an available advanced microLED screen in a limited edition. This is Garmin's top device and engineered to be the only tool needed to explore almost any location and track all your movements.

That makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the regular Fenix 8.

You do get a significant features for your money, with industry-leading workout, movement and outdoor tracking. The full offline maps of the world can automatically direct you back to the trail if you get lost without a phone, and look great on the sizable, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of smartwatch battery life even with the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to competing satellite-capable devices, SOS messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack position sharing – so your friends or family can monitor you while out running, cycling or similar activities – along with emergency orbital SOS alerts.

Location updates and texts over orbital are then billed on top, with more expensive subscriptions including different allowances of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply venture outside 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, dispatch texts and overall stay connected with your relatives and friends.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a set of customisable canned responses you can send to speed things up. Spoken recordings and calls perform OK, though as with most wearables, you’re unlikely going to wish to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own send a URL to selected contacts whenever you start an exercise, so they can follow your live location on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you trust to be aware of your location in case an incident occurs. It has generally worked well, although the actual location has sometimes been delayed when moving in and out of good LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows you how to locate the line of sight 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 safety feature, however it is important to remember that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with services offered via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides recycling schemes on new purchases.

Price

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

Verdict

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

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

It is quite freeing to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the service. 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 weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Cons: extremely expensive, LTE and orbital functions need ongoing subscription, restricted Garmin Pay bank support, speech features are sluggish, basic smartwatch functionality compared with competing watches.
