Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

This newest model of the flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free communication and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED screen in a special edition. It is the brand's premier device and designed to be the single tool needed to venture almost anywhere and monitor every activity.

That makes it an extremely expensive option, priced from £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 edition with microLED screen – nearly twice the price of the regular Fenix 8.

You do receive a significant functionality for your money, with best-in-class fitness, movement and adventure tracking. Its full offline maps of the world can automatically direct you back to the trail if you get lost absent a phone, and look great on the sizable, sharp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service service instead of depending on a watch plan tied to your phone carrier, like other smartwatches. But unlike competing satellite-capable products, SOS messaging is not included for free.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out running, cycling or similar activities – plus SOS orbital SOS messaging.

Check-ins and texts via satellite are then charged on top, with more expensive plans including various quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the service.

Once you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, 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 arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally using text or spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can use to speed things up. Voice messages and calls work acceptably, although as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s great for following competition performance, but it mostly acts as a tool for someone you rely on to know your whereabouts in case something happens. It has typically worked effectively, though the actual location has sometimes been delayed when moving in and out of good LTE coverage.

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

A on-screen assistance displays you how to find the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is important to remember that satellite service is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically repairable with options available through the support portal. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin offers disposal programs on recent purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the service. At least it is not reliant on your phone carrier so functions with all brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but still wants to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED display, monitors everything with premier GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and satellite functions require ongoing subscription, limited Garmin Pay bank support, voice capabilities are slow, basic wearable functionality versus competing watches.
