The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

This most recent version of Garmin's top-tier Fenix adventure watch includes a life-saving capability: no-phone messaging and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular technology, along with an optional state-of-the-art microLED display in a special edition. This is Garmin's top model and engineered to be the only tool needed to venture almost anywhere and monitor all your movements.

This positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

You do get a significant functionality for your investment, with industry-leading workout, activity and adventure monitoring. Its complete offline mapping of the globe can automatically direct you back to the path if you get lost without a phone, and look great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life even with the screen always active, enduring a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your mobile carrier, like other wearables. But in contrast to competing satellite-enabled products, SOS communication is not provided for no cost.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack location sharing – so your contacts or family can keep an eye on you while out running, cycling or similar activities – along with SOS orbital SOS alerts.

Check-ins and texts via satellite are then billed additionally, with higher-tier plans offering various quotas of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the functionality.

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 playing music or comparable activities, but you are able to place and receive calls, send texts and overall keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can send to expedite communication. Voice messages and calls work acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the handiest function. You can set it up to automatically send a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s excellent for monitoring competition progress, but it mostly serves as a utility for someone you rely on to be aware of your location in case something happens. It has generally functioned well, though the actual position has occasionally been delayed when moving in and out of good LTE signal.

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

A guide shows you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available through the customer service site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused materials. Garmin offers recycling schemes on recent purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re out of coverage.

The result is an even more impressive outdoor tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without needing anything else.

It is very liberating to be outside without a phone, but that functionality carries 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. At least it is not reliant on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, cycling or trekking, but still wants to be trackable and reachable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and satellite features need monthly payment, limited Garmin Pay financial support, voice features are slow, basic smartwatch features versus Apple/Google/Samsung watches.
