The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

This latest model of Garmin's top-tier Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED display in a limited edition. It is Garmin's top device and engineered to be the single gadget required to explore virtually any location and track all your movements.

This makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the regular Fenix 8.

You do get a lot of features for your investment, with industry-leading fitness, activity and outdoor monitoring. The full offline maps of the world can automatically guide you back to the trail if you lose your way without a phone, and appear great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life despite the display always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. However unlike competing satellite-capable devices, emergency messaging is not included for free.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messages, calls and LiveTrack location sharing – so your friends or family can monitor you while engaged in running, biking or similar pursuits – along with SOS satellite SOS alerts.

Check-ins and texts via satellite are then charged on top, with higher-tier subscriptions including different quotas of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using typed or spoken communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a phone number is enough to sign up for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned responses you can use to expedite communication. Voice messages and calls work acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to chosen contacts whenever you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to know your location in case something happens. It has generally worked effectively, although the real position has occasionally been delayed when moving in and out of good LTE signal.

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

A on-screen assistance displays you how to find the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that orbital service is restricted to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with services offered through the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled components. Garmin offers disposal programs on recent purchases.

Cost

The Fenix 8 Pro is priced 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).

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

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

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but still desires to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: very expensive, LTE and satellite features need monthly payment, restricted Garmin Pay bank support, voice capabilities are sluggish, basic smartwatch features compared with competing watches.
