The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

The most recent iteration of Garmin's premium Fenix outdoor timepiece introduces a life-saving feature: no-phone messaging and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding new cellular technology, plus an available state-of-the-art microLED display in a special edition. It is the brand's premier device and designed to be the single tool required to venture almost anywhere and monitor every activity.

This positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the price of the standard Fenix 8.

You do receive a lot of features for your money, with industry-leading fitness, movement and adventure monitoring. Its full offline mapping of the world can automatically guide you back to the path if you get lost absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life even with the display always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your mobile carrier, like other smartwatches. But in contrast to competing satellite-enabled products, emergency communication is not included for free.

Rather, plans start at £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while out running, cycling or similar activities – plus SOS satellite SOS messaging.

Location updates and texts over orbital are then charged on top, with higher-tier plans including different allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

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

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth using text or voice communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can send to speed things up. Spoken messages and calls perform OK, although as with the majority of smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to chosen contacts every time you begin an activity, so they can track your real time position on a map. It’s great for monitoring competition performance, but it primarily serves as a utility for someone you trust to know your location in case something happens. It has typically worked well, although the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that orbital service is limited to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options offered via the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost 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, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly remarkable adventure tool for those that want to be phone-free. If you wish to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

This is very liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it isn’t dependent on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but still desires to be locatable and reachable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely costly, LTE and orbital features require ongoing payment, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, basic smartwatch features compared with Apple/Google/Samsung watches.
