Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Texting

The newest version of Garmin's premium Fenix adventure watch includes a potentially lifesaving capability: phone-free communication and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new mobile technology, along with an optional advanced microLED display in a special edition. It is the brand's top device and engineered to be the single gadget required to explore almost anywhere and monitor all your movements.

That makes it an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the standard Fenix 8.

You do get a lot of features for your investment, with industry-leading workout, movement and adventure monitoring. The full offline mapping of the globe can automatically direct you back to the path if you get lost without a phone, and look great on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite service service rather than depending on a watch plan linked to your phone carrier, like other smartwatches. However unlike competing satellite-enabled products, SOS communication is not provided for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE text and audio messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while engaged in jogging, cycling or comparable activities – along with SOS satellite SOS alerts.

Check-ins and texts via orbital are then billed on top, with higher-tier subscriptions including various allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you simply venture outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you are able to make and take calls, send texts and generally stay connected with your family and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using typed or spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It has a collection of customisable canned replies you can use to expedite communication. Spoken recordings and calls perform acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a link to chosen contacts every time you begin an exercise, so they can follow your live position on a map. It’s excellent for monitoring race progress, but it mostly serves as a tool for someone you trust to be aware of your location in case an incident occurs. It has generally worked effectively, although the actual position has occasionally lagged when transitioning in and out of good LTE signal.

These features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A guide 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 lifeline, however it is important to note that satellite coverage is limited to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services offered via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused materials. Garmin offers disposal schemes on new purchases.

Cost

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

Conclusion

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without coverage.

The result is an even more remarkable adventure tool for those that desire to be phone-free. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

It is very liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to provide the service. At least it is not reliant on your phone carrier so works with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or hiking, but still wants to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and orbital functions require ongoing payment, restricted Garmin Pay financial compatibility, voice features are sluggish, basic wearable functionality versus competing watches.
