Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for No-Phone Messaging

The latest iteration of Garmin's premium Fenix outdoor watch brings a life-saving capability: phone-free messaging and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new mobile technology, plus an optional advanced microLED screen in a special edition. It is the brand's premier model and designed to be the single tool required to venture almost any location and track every activity.

This positions it as an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the standard Fenix 8.

You do get a significant features for your investment, with best-in-class fitness, activity and adventure tracking. Its complete offline maps 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 display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an extra day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your phone carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled devices, emergency communication is not included 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 tracking – so your friends or loved ones can keep an eye on you while engaged in running, cycling or comparable activities – along with SOS orbital SOS messaging.

Location updates and texts over orbital are then charged additionally, with more expensive subscriptions offering different quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you simply venture outside without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you can make and take calls, dispatch texts and generally keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or voice messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can send to speed things up. Voice recordings and calls work acceptably, although as with most wearables, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically send a URL to chosen contacts every time you start an exercise, so they can follow your live location on a map. It’s excellent for following race performance, but it primarily acts as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, though the actual location has sometimes been delayed when moving in and out of good LTE signal.

All of these capabilities are available on other Garmin devices 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 transmit texts, position updates and SOS SOS.

A guide displays you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is essential to remember that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with options available via the support portal. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is quite freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but still desires to be locatable and reachable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED display, monitors everything with premier GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital features require ongoing subscription, limited Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable features versus Apple/Google/Samsung watches.
