Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

This most recent version of Garmin's flagship Fenix adventure watch introduces a potentially lifesaving capability: no-phone messaging and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular tech, plus an available advanced microLED display in a special edition. It is Garmin's top device and engineered to be the only gadget required to venture virtually any location and track all your movements.

That makes it an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the price of the standard Fenix 8.

Users get a significant functionality for your investment, with best-in-class fitness, movement and outdoor tracking. The complete offline mapping of the world can seamlessly guide you return to the path if you get lost absent a phone, and look excellent on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your mobile provider, as with other smartwatches. But unlike competing satellite-enabled devices, emergency communication is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in jogging, biking or comparable activities – plus emergency satellite SOS alerts.

Check-ins and messages over satellite are then billed on top, with more expensive plans including various quotas of orbital usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can test out 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 playing music or similar tasks, but you are able to place and receive calls, send texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a phone number is sufficient to register for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a set of customisable canned responses you can use to speed things up. Spoken recordings and calls work acceptably, although as with most wearables, you’re not going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts whenever you start an exercise, so they can follow your live position on a map. It’s great for monitoring race performance, but it primarily serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally worked well, though the real location has occasionally lagged when transitioning in and out of strong LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide displays you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though it is important to note that satellite service is restricted to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with services available via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal programs on new purchases.

Price

This 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 takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without signal.

The result is an increasingly impressive adventure device for those that desire to be unplugged. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, cycling or hiking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and satellite features need monthly payment, restricted Garmin Pay bank compatibility, speech capabilities are slow, basic smartwatch features compared with competing watches.
