Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Texting

The newest model of the flagship Fenix outdoor timepiece brings a life-saving feature: phone-free messaging and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is the brand's premier model and designed to be the single tool needed to venture almost anywhere and monitor every activity.

That positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the regular Fenix 8.

You do receive a lot of features for your money, with best-in-class fitness, movement and adventure monitoring. The complete offline mapping of the globe can seamlessly direct you return to the trail if you lose your way without a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your mobile provider, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, emergency messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, biking or comparable activities – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive plans offering various allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the service.

Once you have completed setup, you simply venture the door without your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and companions.

When you message 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 app, you can then communicate reciprocally using text or voice communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can use to speed things up. Voice recordings and calls work OK, although as with most smartwatches, you’re not going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to selected contacts every time you start an activity, so they can track your real time position on a map. It’s excellent for following race performance, but it primarily acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally worked effectively, though the actual location has sometimes lagged when moving in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to locate the clear view to the satellite, which then sends and receives communications 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 restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options offered via the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused components. Garmin offers disposal programs on new purchases.

Cost

This Fenix 8 Pro is priced 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).

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

The result is an increasingly impressive adventure device for those that want to be unplugged. 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 requiring additional gear.

This is very freeing to be outside without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to enable the features. At least it is not dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.
