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

This latest iteration of Garmin's top-tier Fenix outdoor timepiece introduces a life-saving feature: no-phone messaging and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an optional state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and designed to be the single gadget required to venture almost anywhere and track all your movements.

That makes it an very expensive option, starting at £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 display – nearly double the cost of the standard Fenix 8.

You do receive a significant features for your investment, with industry-leading workout, activity and outdoor monitoring. The complete offline maps of the globe can seamlessly direct you back to the path if you get lost without a phone, and look great on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan linked to your mobile provider, like other wearables. But 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 unlimited LTE SMS and audio messages, calls and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in jogging, biking or comparable pursuits – along with SOS orbital SOS messaging.

Check-ins and texts via satellite are then billed on top, with higher-tier plans including different allowances of orbital usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the service.

Once you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can place and receive calls, send texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally using typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a phone number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. Spoken messages and calls work OK, although as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to selected contacts every time you start an activity, so they can track your live position on a map. It’s great for monitoring race performance, but it primarily serves as a utility for someone you trust to know your location in case something happens. It has typically functioned well, though the real position has occasionally lagged when moving in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to remember that orbital coverage is limited to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services available through the support portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled components. Garmin offers recycling programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly impressive adventure device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it isn’t dependent on your phone provider so functions with all brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when jogging, biking or hiking, but nevertheless desires to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, tracks all activities with premier GPS, integrated 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.

Drawbacks: extremely expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
