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

The latest iteration of Garmin's flagship Fenix outdoor watch includes a potentially lifesaving feature: no-phone communication and emergency alerts via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new cellular tech, along with an available advanced microLED screen in a limited edition. This is the brand's top model and engineered to be the single tool required to venture virtually any location and track all your movements.

That makes it an very pricey proposition, priced from £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 price of the regular Fenix 8.

Users receive a lot of features for your money, with industry-leading workout, movement and outdoor tracking. Its full offline maps of the world can seamlessly direct you return to the trail if you get lost absent a phone, and look excellent on the large, sharp and super-bright touchscreen.

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

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your mobile carrier, like other wearables. But in contrast to competing satellite-capable devices, emergency messaging is not provided for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while out jogging, biking or similar activities – plus emergency satellite SOS messaging.

Location updates and messages over orbital are then billed additionally, with more expensive plans including various quotas of satellite use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your relatives and friends.

When you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via typed or voice communications, and initiate voice calls. Your contact does not need 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 small on-screen keyboard is slow. It has a collection of customisable pre-set responses you can send to speed things up. Voice messages and calls work OK, though as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can set it up to on its own send a link to chosen contacts whenever you start an activity, so they can track your live location on a map. It’s excellent for following race progress, but it mostly acts as a utility for someone you trust to know your location in case an incident occurs. It has typically worked well, although the real location has occasionally been delayed when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight 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 safety feature, though it is important to note that satellite coverage is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services offered via the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin provides 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 additional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

It is quite liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to provide the features. Fortunately it is not dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED display, tracks everything with premier GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and satellite functions need ongoing subscription, restricted Garmin Pay bank compatibility, voice features are slow, limited smartwatch functionality compared with competing watches.
