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

This newest iteration of Garmin's flagship Fenix adventure watch introduces a potentially lifesaving feature: no-phone communication and emergency alerts via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge mobile tech, along with an available state-of-the-art microLED display in a special edition. This is the brand's top model and designed to be the only gadget needed to explore virtually anywhere and monitor every activity.

This positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the standard Fenix 8.

Users get a lot of features for your investment, with best-in-class workout, activity and outdoor monitoring. The full offline mapping of the world can seamlessly direct you back to the path if you lose your way without a phone, and look great on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your phone provider, like other smartwatches. However unlike Apple or Google's satellite-capable devices, emergency messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while out running, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with higher-tier subscriptions including various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you just venture outside without your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can make and take calls, dispatch texts and overall stay connected with your relatives and companions.

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

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set responses you can send to speed things up. Spoken messages and calls perform acceptably, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest function. You can configure to on its own send a URL to selected contacts every time you start an activity, so they can track your live position on a map. It’s great for monitoring competition performance, but it primarily acts as a utility for someone you rely on to know your whereabouts in case something happens. It has typically worked effectively, although the actual location has occasionally lagged when moving in and out of strong LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

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

Environmental Impact

The watch is generally serviceable with services available via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers recycling programs on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans 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 incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you want to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin does so without requiring anything else.

This is very liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it isn’t dependent on your phone provider so works with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very expensive, LTE and orbital functions require monthly subscription, restricted Garmin Pay bank support, voice capabilities are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
