The Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Messaging

This newest model of the flagship Fenix adventure timepiece includes a life-saving feature: phone-free communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an optional advanced microLED screen in a limited edition. It is the brand's top model and engineered to be the single gadget needed to venture almost any location and track every activity.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £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.

You do receive a significant functionality for your money, with best-in-class fitness, activity and adventure tracking. The full offline maps of the world can automatically guide you return to the path if you get lost absent a phone, and appear great on the large, crisp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra 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 proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan tied to your mobile carrier, like other wearables. But unlike competing satellite-capable products, SOS messaging is not included for no cost.

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

Check-ins and messages via satellite are then billed additionally, with more expensive plans including various allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, send texts and overall stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable pre-set replies you can use to speed things up. Voice messages and calls work acceptably, though as with the majority of wearables, you’re unlikely going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful function. You can configure to automatically send a URL to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for monitoring competition progress, but it mostly serves as a utility for someone you trust to be aware of your location in case something happens. It has generally functioned well, although the actual location has sometimes been delayed when transitioning in and out of good LTE signal.

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

A guide shows you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though it is essential to remember that orbital service is restricted to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services available via the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely 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 functionality comes at quite a cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it is not dependent on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors all activities with premier GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Cons: extremely costly, LTE and satellite features need ongoing payment, restricted Garmin Pay financial support, speech features are slow, limited wearable features versus competing watches.
