The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The latest model of the flagship Fenix outdoor watch includes a life-saving capability: no-phone communication and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new cellular tech, along with an available advanced microLED screen in a limited edition. This is Garmin's top device and engineered to be the single tool needed to venture virtually anywhere and monitor all your movements.

That makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the standard Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, activity and adventure monitoring. The full offline mapping of the globe can seamlessly guide you back to the path if you get lost absent a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, 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 display on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite service service instead of relying on a watch plan linked to your phone carrier, as with other wearables. But in contrast to Apple or Google's satellite-capable products, emergency communication is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in running, biking or comparable pursuits – plus SOS satellite SOS alerts.

Check-ins and texts via satellite are then charged additionally, with higher-tier plans offering various quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via text or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can use to speed things up. Voice messages and calls perform acceptably, though as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own transmit a URL to chosen contacts every time you start an exercise, so they can follow your live position on a map. It’s excellent for following race performance, but it mostly serves as a tool for someone you rely on to know your whereabouts in case something happens. It has generally worked effectively, although the actual location has sometimes lagged when moving in and out of strong LTE coverage.

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

A guide shows you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that orbital coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services available via the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks 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 additional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without signal.

The result is an increasingly remarkable outdoor device for those that desire to be phone-free. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

It is very freeing to be outdoors without a phone, but that capability carries a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. Fortunately it isn’t reliant on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, biking or hiking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, monitors everything with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic wearable functionality compared with competing watches.
