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 includes a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating new mobile tech, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's top model and engineered to be the single tool required to venture virtually anywhere and monitor all your movements.

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

You do get a significant functionality for your investment, with industry-leading fitness, activity and adventure monitoring. Its complete offline maps of the world can seamlessly guide you return to the path if you lose your way without a phone, and look excellent on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and orbital service plan rather than depending on a watch plan tied to your mobile carrier, like other smartwatches. But in contrast to competing satellite-capable products, emergency messaging is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and texts over orbital are then charged additionally, with more expensive plans offering different quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have got it set up, you just venture outside without your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you are able to make and take calls, send texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally using typed or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It has a collection of personalizable canned responses you can use to expedite communication. Spoken messages and calls work OK, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to chosen contacts whenever you start an exercise, so they can track your live position on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally worked effectively, though the actual position has sometimes lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin watches 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 send texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is essential to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with services offered via the customer service portal. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re out of coverage.

The result is an even more remarkable adventure tool for those that desire to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the remote areas, the Garmin accomplishes this without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it is not dependent on your phone provider so works with any make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, cycling or hiking, but still wants to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and satellite functions require ongoing payment, restricted Garmin Pay financial compatibility, speech features are slow, basic smartwatch features versus Apple/Google/Samsung watches.
