Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for No-Phone Messaging

This most recent model of Garmin's top-tier Fenix outdoor timepiece includes a life-saving capability: no-phone communication and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's top model and designed to be the single tool required to explore almost anywhere and monitor all your movements.

This positions it as an very 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 display – nearly twice the price of the regular Fenix 8.

You do receive a lot of features for your money, with industry-leading workout, activity and adventure tracking. Its full offline maps of the globe can automatically guide you back to the trail if you lose your way without a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your phone carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-capable devices, SOS communication is not provided for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, calls and LiveTrack position tracking – so your friends or family can monitor you while engaged in jogging, biking or comparable pursuits – plus SOS satellite SOS messaging.

Location updates and messages over orbital are then billed additionally, with more expensive plans including different quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you simply head out 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 place and receive calls, send texts and generally keep in touch with your family and companions.

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

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable canned replies you can send to expedite communication. Voice messages and calls perform acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can set it up to automatically transmit a link to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s great for monitoring race progress, but it mostly serves as a utility for someone you trust to be aware of your location in case something happens. It has typically worked effectively, though the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is essential to remember that satellite coverage is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered through the customer service portal. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor tool for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the remote areas, the Garmin does so without requiring anything else.

It is quite freeing to be outside without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to provide the service. At least it is not dependent on your phone provider so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, tracks all activities with premier GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital features need monthly subscription, limited Garmin Pay financial compatibility, voice capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
