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

The latest iteration of Garmin's premium Fenix adventure watch includes a potentially lifesaving feature: no-phone communication and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge mobile technology, plus an optional state-of-the-art microLED display in a limited edition. It is the brand's premier device and engineered to be the only gadget required to explore almost anywhere and track every activity.

That positions it as an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the standard Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class fitness, movement and outdoor monitoring. The complete offline maps of the globe can automatically direct you return to the path if you lose your way without a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the display always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service service instead of relying on a watch plan linked to your mobile carrier, like other wearables. 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 position tracking – so your contacts or family can monitor you while out jogging, biking or comparable activities – along with emergency orbital SOS alerts.

Check-ins and texts over satellite are then billed on top, with higher-tier subscriptions offering different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and generally keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via typed or spoken messages, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned replies you can send to expedite communication. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a link to selected contacts every time you start an exercise, so they can track your live position on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned well, although the real position has sometimes been delayed when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A guide displays you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is essential to remember that orbital service is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options available via the customer service portal. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling programs on new 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 builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor device for those that desire to be unplugged. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

This is very freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to enable the features. Fortunately it is not reliant on your phone provider so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED display, monitors all activities with premier GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and orbital features require ongoing payment, limited Garmin Pay financial compatibility, speech features are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
