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

The newest iteration of Garmin's top-tier Fenix outdoor watch introduces a life-saving capability: no-phone messaging and SOS alerts using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new mobile tech, along with an available state-of-the-art microLED display in a limited edition. This is the brand's premier device and designed to be the only gadget needed to explore almost any location and monitor all your movements.

That positions it as an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model 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 features for your investment, with industry-leading fitness, activity and adventure monitoring. The complete offline mapping of the globe can automatically guide you return to the path if you get lost without a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the screen always active, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your phone provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, cycling or comparable activities – along with SOS orbital SOS messaging.

Check-ins and texts via satellite are then charged additionally, with more expensive plans offering different allowances of satellite usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture the door without your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you can make and take calls, send texts and generally keep in touch with your family and friends.

When you text someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using text or voice messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to speed things up. Spoken messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s great for monitoring race performance, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has generally worked effectively, although the real position has sometimes been delayed when transitioning in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, though it is important to remember that orbital coverage is limited to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options offered via the customer service portal. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling schemes 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).

Verdict

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

Outcome is an even more remarkable outdoor device for those that desire to be unplugged. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is very freeing to be outdoors without a phone, but that capability carries quite a price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. At least it isn’t reliant on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, biking or trekking, but still desires to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very expensive, LTE and satellite functions require ongoing payment, limited Garmin Pay financial support, speech capabilities are slow, limited wearable features compared with competing watches.
