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

This latest iteration of the flagship Fenix adventure timepiece introduces a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular tech, plus an available advanced microLED display in a limited edition. It is Garmin's top model and engineered to be the single gadget required to venture almost anywhere and monitor every activity.

That 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the standard Fenix 8.

Users get a significant features for your money, with industry-leading fitness, activity and outdoor tracking. Its full offline maps of the world can seamlessly direct you back to the path if you lose your way without a phone, and appear great on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your phone carrier, as with other wearables. But in contrast to competing satellite-capable devices, emergency communication is not included for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your friends or family can keep an eye on you while engaged in running, biking or comparable pursuits – plus emergency satellite SOS alerts.

Location updates and texts via satellite are then charged additionally, with more expensive subscriptions including various quotas of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the service.

After you have completed setup, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and companions.

When you message someone, Garmin sends them an SMS from a random 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 typed or voice communications, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Messaging on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned responses you can use to expedite communication. Voice messages and calls work acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can set it up to automatically send a link to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s great for monitoring competition performance, but it primarily serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned effectively, although the real position has occasionally lagged when moving in and out of good LTE signal.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide shows you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is essential to note that orbital service is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered through the support portal. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused 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 optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

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

The result is an even more remarkable outdoor device for those that desire to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is very liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the features. Fortunately it is not dependent on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when jogging, biking or trekking, but still wants to be locatable and contactable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite functions require ongoing payment, restricted Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
