Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for No-Phone Texting

This newest version of Garmin's top-tier Fenix adventure timepiece introduces a life-saving feature: no-phone communication and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED display in a limited edition. This is the brand's top model and designed to be the only tool required to venture almost any location and monitor all your movements.

That makes it an very pricey option, priced from £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 twice the cost of the regular Fenix 8.

Users get a significant features for your money, with best-in-class workout, activity and outdoor monitoring. The complete offline mapping of the world can automatically guide you back to the trail if you lose your way without a phone, and look great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version found in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life even with the display always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

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

Instead, subscriptions start at £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out running, biking or similar activities – along with emergency satellite SOS alerts.

Location updates and texts over satellite are then billed additionally, with more expensive plans including various quotas of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the service.

After you have completed setup, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you can place and receive calls, dispatch texts and generally keep in touch with your family and companions.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using text or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable canned responses you can send to expedite communication. Voice messages and calls work OK, although as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful function. You can configure to on its own send a URL to selected contacts every time you begin an activity, so they can track your real time location on a map. It’s excellent for following competition progress, but it primarily serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned effectively, though the actual location has occasionally lagged when moving in and out of strong LTE coverage.

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

A guide 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 surprisingly easy to use and could be a crucial safety feature, however it is essential to note that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available via the support site. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

This 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).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable adventure tool for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is quite freeing to be outdoors 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 plan to provide the features. At least it isn’t reliant on your phone carrier so works 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 still desires to be trackable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED display, tracks everything with premier GPS, integrated flashlight, phone and standalone 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 touchscreen.

Cons: very expensive, LTE and satellite features require monthly payment, limited Garmin Pay bank compatibility, speech features are slow, limited wearable functionality versus competing watches.
