Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for No-Phone Texting

The most recent model of Garmin's flagship Fenix outdoor watch brings a life-saving feature: no-phone messaging and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge cellular technology, plus an optional advanced microLED display in a special edition. This is Garmin's premier device and designed to be the only gadget needed to explore almost anywhere and monitor every activity.

This makes it an very 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 variant with microLED display – nearly twice the price of the regular Fenix 8.

You do get a significant functionality for your investment, with industry-leading workout, movement and adventure tracking. Its full offline mapping of the globe can seamlessly guide you back to the trail if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your mobile provider, like other smartwatches. But in contrast to competing satellite-capable devices, emergency communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messages, calls and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out jogging, cycling or similar pursuits – along with emergency satellite SOS alerts.

Location updates and messages via satellite are then billed additionally, with higher-tier plans offering different allowances of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just 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 slow. It has a set of customisable pre-set replies you can use to expedite communication. Voice recordings and calls work OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is less than ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to chosen contacts whenever you start an activity, so they can follow your real time location on a map. It’s excellent for following competition progress, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned well, though the actual position has sometimes been delayed when transitioning in and out of good LTE signal.

All of these features are available on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance 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 unexpectedly straightforward to use and could be a crucial safety feature, however it is important to remember that satellite service is limited to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services offered via the support portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled materials. Garmin offers recycling schemes on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly impressive adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

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

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

Pros: LTE and orbital messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in torch, phone and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very costly, LTE and orbital functions need monthly payment, restricted Garmin Pay financial support, speech features are sluggish, basic wearable features versus competing watches.
