Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Messaging

This newest version of Garmin's top-tier Fenix outdoor timepiece brings a potentially lifesaving feature: no-phone messaging and emergency alerts via 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new mobile technology, plus an optional advanced microLED display in a special edition. It is the brand's top model and designed to be the single gadget needed to explore virtually any location and monitor every activity.

This makes it an very expensive option, 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 edition with microLED screen – almost twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your money, with best-in-class workout, activity and outdoor tracking. The complete offline mapping of the globe can automatically guide you return to the path if you get lost without a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your mobile provider, like other wearables. However in contrast to Apple or Google's satellite-capable products, emergency communication is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, cycling or comparable activities – plus emergency satellite SOS messaging.

Check-ins and messages over satellite are then billed on top, with more expensive plans including different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have completed setup, you just venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, dispatch texts and overall keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable pre-set replies you can use to speed things up. Spoken recordings and calls work OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can set it up to automatically transmit a link to chosen contacts every time you start an exercise, 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 trust to know your whereabouts in case an incident occurs. It has generally worked well, although the actual location has sometimes been delayed when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide shows you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, though it is essential to remember that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options available via the support portal. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled components. Garmin offers 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 additional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without signal.

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

This is very liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone carrier so works with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital functions need monthly payment, limited Garmin Pay bank support, voice capabilities are slow, limited wearable features versus competing watches.
