Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

The most recent iteration of the flagship Fenix adventure timepiece includes a life-saving feature: no-phone communication and SOS messaging via 4G LTE or orbital connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an optional state-of-the-art microLED screen in a limited edition. It is Garmin's top device and designed to be the only gadget required to venture virtually anywhere and monitor every activity.

This positions it as an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the price of the standard Fenix 8.

Users get a significant functionality for your investment, with industry-leading workout, movement and adventure tracking. The full offline mapping of the globe can seamlessly direct you back to the path if you lose your way absent a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your phone carrier, like other wearables. However in contrast to competing satellite-enabled devices, SOS messaging is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack position sharing – so your friends or family can keep an eye on you while out jogging, biking or similar activities – plus SOS satellite SOS alerts.

Check-ins and messages over orbital are then billed on top, with higher-tier subscriptions including various quotas of orbital use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can use to speed things up. Voice messages and calls work acceptably, though as with most smartwatches, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a URL to chosen contacts every time you start an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition performance, but it primarily acts as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically functioned well, though the actual location has occasionally been delayed when transitioning in and out of good LTE signal.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, though it is important to remember that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through the support portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused components. Garmin provides recycling programs on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it is not reliant on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, biking or trekking, but still desires to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay bank support, speech features are slow, basic smartwatch functionality compared with competing watches.
