Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The most recent model of Garmin's flagship Fenix adventure timepiece introduces a life-saving feature: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, plus an optional advanced microLED screen in a special edition. This is the brand's top model and engineered to be the only gadget needed to venture almost any location and monitor all your movements.

That makes it an extremely expensive 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 display – almost double the price of the standard Fenix 8.

You do get a lot of functionality for your investment, with industry-leading workout, movement and adventure monitoring. Its full offline maps of the globe can automatically direct you back to the path if you get lost without a phone, and look great on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life despite the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and orbital service service rather than depending on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, SOS communication is not provided for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in running, biking or comparable activities – along with emergency satellite SOS messaging.

Check-ins and texts over satellite are then charged on top, with more expensive plans including different allowances of satellite use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth using typed or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, just a mobile number is sufficient to register for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a set of customisable pre-set responses you can use to speed things up. Spoken messages and calls work OK, although as with most wearables, you’re not going to wish to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts every time you begin an activity, so they can follow your live location on a map. It’s great for following competition performance, but it primarily acts as a tool for someone you trust to be aware of your whereabouts in case something happens. It has generally worked well, although the actual location has occasionally lagged when moving in and out of good LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to remember that satellite coverage is limited to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services available through the support portal. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal programs on recent 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re without coverage.

Outcome is an increasingly remarkable adventure device for those that want to be unplugged. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without needing anything else.

It is quite liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. At least it is not dependent on your phone provider so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but still wants to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors all activities with premier GPS, built-in flashlight, voice 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, buttons and touchscreen.

Cons: extremely expensive, LTE and orbital features require monthly subscription, restricted Garmin Pay financial support, voice features are sluggish, limited smartwatch functionality versus competing watches.
