The Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Messaging

This newest iteration of Garmin's premium Fenix adventure watch brings a potentially lifesaving capability: no-phone messaging and emergency alerts via 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an optional state-of-the-art microLED display in a limited edition. This is the brand's top device and designed to be the only tool needed to explore almost any location and monitor all your movements.

That makes it an very pricey proposition, 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 double the cost of the regular Fenix 8.

You do get a significant features for your investment, with industry-leading workout, activity and outdoor monitoring. Its complete offline maps of the globe can automatically direct you back to the path if you get lost without a phone, and look excellent on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a large watch for larger wrists. However 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 Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan tied to your phone carrier, as with other wearables. But in contrast to Apple or Google's satellite-capable products, emergency messaging is not provided for no cost.

Instead, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable activities – along with SOS orbital SOS alerts.

Location updates and messages over orbital are then billed on top, with higher-tier plans including different quotas of satellite usage, climbing 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 head out outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can make and take calls, dispatch texts and overall keep in touch with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth using text or voice communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can use to speed things up. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to selected contacts every time you begin an activity, so they can follow your live position on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically worked well, though the real position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available through the support site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any recycled components. Garmin offers disposal schemes 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 packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more impressive adventure device for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is very liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. At least it is not dependent on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED display, monitors everything with best-in-class GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: extremely costly, LTE and satellite features require ongoing payment, limited Garmin Pay bank support, speech capabilities are slow, basic smartwatch features versus Apple/Google/Samsung watches.
