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

This newest model of the top-tier Fenix adventure watch introduces a potentially lifesaving capability: phone-free communication and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED screen in a special edition. It is the brand's top model and engineered to be the only gadget required to explore almost any location and track every activity.

This makes it an very expensive option, 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 variant with microLED display – nearly twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, activity and outdoor tracking. Its full offline mapping of the globe can seamlessly direct you return to the trail if you get lost absent a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version found in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the display on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company operates its own inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, emergency communication is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack position sharing – so your friends or family can monitor you while out jogging, cycling or comparable pursuits – along with SOS satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with more expensive subscriptions offering various allowances of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

After you have completed setup, you simply head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your family and companions.

Whenever you message 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 app, you can then communicate reciprocally via text or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can use to expedite communication. Voice messages and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can configure to automatically transmit a link to chosen contacts every time you begin an activity, so they can follow your live position on a map. It’s great for monitoring race progress, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically functioned well, though the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

All of these features 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 emergency SOS.

A guide displays you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options offered via the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal schemes on recent purchases.

Price

The Fenix 8 Pro is priced 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

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the service. Fortunately it is not dependent on your phone provider so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors everything with premier GPS, integrated torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and orbital functions need monthly subscription, limited Garmin Pay bank support, speech capabilities are sluggish, limited smartwatch functionality compared with competing watches.
