Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Connectivity for Phone-Free Messaging

The latest version of Garmin's flagship Fenix adventure timepiece includes a potentially lifesaving capability: no-phone communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by adding new cellular tech, along with an optional advanced microLED display in a limited edition. This is Garmin's top device and engineered to be the only tool required to venture almost any location and track every activity.

This positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the regular Fenix 8.

You do get a significant functionality for your investment, with best-in-class fitness, activity and outdoor tracking. The full offline mapping of the globe can seamlessly guide you return to the path if you get lost absent a phone, and look excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of watch battery life even with the screen always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan tied to your mobile provider, like other wearables. But unlike Apple or Google's satellite-enabled devices, emergency communication is not included for free.

Rather, plans start at £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messaging, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in running, biking or similar pursuits – plus SOS satellite SOS alerts.

Check-ins and messages over orbital are then billed additionally, with higher-tier plans offering various quotas of orbital usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have completed setup, you simply venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar 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 sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth via text or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to register for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can use to speed things up. Voice messages and calls work OK, though as with most wearables, you’re not going to wish to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own transmit a link to selected contacts whenever you begin an exercise, so they can follow your real time location on a map. It’s excellent for following competition performance, but it primarily serves as a utility for someone you trust to be aware of your location in case something happens. It has generally worked well, although the real location has sometimes been delayed when moving in and out of strong LTE coverage.

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

A guide 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 surprisingly straightforward to use and could be a crucial lifeline, however it is essential to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered via the customer service site. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch lacks any recycled materials. Garmin offers recycling programs on recent purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This 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 satellite communication, location update and SOS SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you wish 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 additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the features. At least it is not dependent on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors all activities with best-in-class GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital features require monthly payment, limited Garmin Pay financial compatibility, speech features are sluggish, limited smartwatch functionality versus competing watches.
