Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

The latest iteration of Garmin's premium Fenix outdoor watch brings a potentially lifesaving feature: phone-free messaging and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new mobile tech, plus an optional state-of-the-art microLED display in a special edition. This is the brand's premier model and engineered to be the only gadget required to venture almost anywhere and monitor every activity.

That makes it an extremely pricey proposition, priced from £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 display – almost double the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with industry-leading workout, activity and adventure tracking. Its complete offline maps of the world can automatically direct you back to the trail if you get lost absent a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life despite the display always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your mobile provider, like other wearables. But unlike Apple or Google's satellite-capable devices, emergency messaging is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and voice messaging, calls and LiveTrack location sharing – so your friends or family can monitor you while out running, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and texts via orbital are then charged additionally, with higher-tier subscriptions including various quotas of orbital usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and generally stay connected with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable canned replies you can use to speed things up. Voice recordings and calls perform OK, though as with most smartwatches, 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 configure to automatically transmit a link to selected contacts every time you start an activity, so they can track your real time position on a map. It’s great for monitoring race progress, but it mostly acts as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally worked well, though the actual location has occasionally been delayed when transitioning in and out of good LTE coverage.

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

A on-screen assistance displays you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered via the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides recycling programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin does so without requiring anything else.

It is quite liberating to be outside without a phone, but that functionality carries a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the features. At least it is not reliant on your phone provider so functions with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but still desires to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very costly, LTE and satellite functions need ongoing payment, limited Garmin Pay financial support, voice features are slow, basic wearable features versus competing watches.
