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

This newest iteration of the premium Fenix adventure watch includes a potentially lifesaving feature: phone-free messaging and SOS alerts using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular technology, plus an optional state-of-the-art microLED screen in a special edition. It is the brand's top model and designed to be the single gadget needed to venture almost any location and monitor every activity.

This makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the cost of the standard Fenix 8.

Users receive a lot of features for your money, with best-in-class workout, activity and outdoor tracking. Its complete offline mapping of the globe can automatically guide you back to the path if you lose your way absent a phone, and appear great on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed does have an additional day of smartwatch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your phone carrier, like other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack location sharing – so your friends or family can monitor you while out running, cycling or similar activities – along with SOS orbital SOS alerts.

Check-ins and messages via satellite are then billed additionally, with more expensive subscriptions including different quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the service.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using text or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can send to speed things up. Voice messages and calls perform acceptably, though as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically send a URL to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s great for monitoring race progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, though the real position has sometimes been delayed when moving in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A guide shows 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 crucial safety feature, however it is essential to remember that satellite coverage is limited to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services offered via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused components. Garmin offers disposal programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of coverage.

The result is an even more impressive outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite freeing to be outdoors without a phone, but that capability carries a significant price, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to provide the service. At least it isn’t dependent on your phone provider so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED display, tracks everything with best-in-class GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very expensive, LTE and satellite features require monthly subscription, limited Garmin Pay bank support, speech capabilities are sluggish, limited wearable features compared with competing watches.
