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

The newest version of Garmin's top-tier Fenix adventure timepiece introduces a life-saving capability: phone-free communication and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular technology, plus an optional advanced microLED display in a limited edition. It is Garmin's top model and designed to be the single gadget needed to explore almost any location and track all your movements.

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

You do get a lot of functionality for your money, with industry-leading fitness, activity and outdoor tracking. The complete offline maps of the world can automatically guide you back to the trail if you get lost absent a phone, and look great on the large, crisp and super-bright display.

This 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 big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your phone provider, like other smartwatches. However in contrast to Apple or Google's satellite-capable products, emergency communication is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can monitor you while out running, cycling or comparable pursuits – along with emergency satellite SOS alerts.

Check-ins and messages over orbital are then charged additionally, with more expensive subscriptions including various allowances of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the service.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and generally stay connected with your family and companions.

When you text 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 message back and forth via typed or spoken communications, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned replies you can send to expedite communication. Spoken recordings and calls perform acceptably, although as with most smartwatches, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a URL to selected contacts every time you start an exercise, so they can follow your real time position on a map. It’s great for monitoring race progress, but it primarily acts as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically worked effectively, though the real position has sometimes been delayed when transitioning in and out of good LTE coverage.

These features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is essential to remember that orbital service is restricted to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with services offered through the support site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused components. Garmin provides recycling schemes on recent purchases.

Price

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor device for those that want to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone provider so functions with all make of smartphone and network.

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

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with best-in-class GPS, integrated flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: very expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay financial compatibility, speech features are sluggish, basic wearable functionality versus Apple/Google/Samsung watches.
