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

The most recent iteration of the flagship Fenix outdoor timepiece includes a life-saving feature: no-phone communication and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular technology, along with an available advanced microLED screen in a limited edition. It is the brand's top model and engineered to be the only gadget needed to explore virtually any location and track every activity.

This positions it as an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the price of the standard Fenix 8.

Users get a significant features for your money, with best-in-class workout, activity and outdoor tracking. Its full offline maps of the world can automatically guide you return to the trail if you get lost without a phone, and appear great on the large, sharp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone provider, like other smartwatches. But in contrast to competing satellite-capable products, SOS messaging is not provided for no cost.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your friends or family can monitor you while engaged in running, biking or comparable activities – along with emergency satellite SOS messaging.

Location updates and messages over satellite are then billed on top, with more expensive plans offering various allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the service.

After you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using text or spoken messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a mobile 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 set of personalizable canned replies you can use to expedite communication. Spoken recordings and calls work OK, although as with most wearables, you’re unlikely going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to automatically transmit 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 competition performance, but it mostly acts as a tool for someone you trust to know your location in case an incident occurs. It has generally functioned well, although the actual position has occasionally lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A guide displays 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, however it is important to note that satellite service is limited to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the customer service portal. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin provides disposal programs on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that functionality 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 features. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, biking or trekking, but nevertheless desires to be locatable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital features need ongoing subscription, limited Garmin Pay financial compatibility, speech features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
