Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This most recent version of Garmin's premium Fenix outdoor watch introduces a life-saving capability: no-phone messaging and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new mobile technology, plus an optional advanced microLED screen in a special edition. This is Garmin's top device and designed to be the only gadget required to explore almost anywhere and monitor every activity.

This makes it an very expensive proposition, starting at £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 variant with microLED display – almost twice the price of the standard Fenix 8.

You do get a lot of functionality for your money, with industry-leading workout, activity and adventure monitoring. Its full offline mapping of the globe can seamlessly guide you return to the path if you lose your way absent a phone, and look excellent on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital service plan rather than depending on a watch plan linked to your phone provider, as with other wearables. However unlike Apple or Google's satellite-capable devices, SOS communication is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while out jogging, biking or similar activities – plus emergency orbital SOS messaging.

Location updates and texts via satellite are then charged additionally, with higher-tier subscriptions offering various allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary 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 is not required to have a Garmin profile 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 includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken messages and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts whenever you begin an exercise, so they can follow your live location on a map. It’s great for monitoring competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned effectively, though the real location has sometimes been delayed 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 areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is important to remember that orbital coverage is restricted to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the customer service portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers recycling 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re out of coverage.

The result is an even more remarkable adventure device for those that want to be unplugged. If you wish to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without needing anything else.

It is very liberating to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it is not dependent on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, cycling or trekking, but still wants to be trackable and contactable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features require ongoing payment, limited Garmin Pay financial compatibility, voice features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
