The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Texting

This newest model of the top-tier Fenix outdoor watch includes a life-saving feature: phone-free communication and SOS alerts using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, along with an available state-of-the-art microLED screen in a special edition. This is the brand's premier model and engineered to be the single tool required to explore almost any location and monitor every activity.

That makes it an very pricey option, starting at £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 screen – almost double the price of the standard Fenix 8.

You do get a lot of functionality for your money, with best-in-class fitness, movement and outdoor monitoring. The complete offline mapping of the world can seamlessly direct you back to the trail if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an extra day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your mobile carrier, like other smartwatches. However unlike competing satellite-enabled devices, emergency messaging is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, cycling or similar activities – plus SOS orbital SOS alerts.

Location updates and texts via satellite are then billed additionally, with higher-tier plans offering various quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you just head out outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally using typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account 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 tiny on-screen keyboard is slow. It includes a set of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform OK, though as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically send a URL to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for monitoring race progress, but it mostly acts as a tool for someone you trust to be aware of your location in case an incident occurs. It has typically functioned well, although the real location has occasionally been delayed when moving in and out of strong LTE signal.

These features are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide displays you how to locate the clear view to the satellite, 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 essential to remember that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with services available through the support portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal programs on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin does so without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the service. At least it is not dependent on your phone carrier so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but still wants 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 screen, tracks all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and satellite features require monthly payment, restricted Garmin Pay bank support, speech features are slow, basic smartwatch functionality versus Apple/Google/Samsung watches.
