The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Texting

The latest model of the flagship Fenix adventure timepiece brings a potentially lifesaving capability: phone-free messaging and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new mobile tech, plus an available advanced microLED display in a special edition. This is the brand's top model and designed to be the only gadget required to venture virtually anywhere and track every activity.

This 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the regular Fenix 8.

You do receive a lot of features for your money, with best-in-class fitness, activity and adventure tracking. The full offline maps of the world can automatically direct you return to the path if you lose your way absent a phone, and look excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an additional day of watch battery life despite the display on all the time, lasting a reliable 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 rather than depending on a watch plan linked to your mobile carrier, as with other smartwatches. But unlike competing satellite-enabled devices, emergency messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack position sharing – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – plus emergency orbital SOS messaging.

Location updates and texts over orbital are then billed on top, with more expensive subscriptions offering different allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

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

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth via text or voice communications, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can send to speed things up. Spoken recordings and calls perform acceptably, though as with the majority of smartwatches, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a link to selected contacts whenever you begin an activity, so they can track your real time location on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you trust to be aware of your location in case an incident occurs. It has typically worked effectively, although the real position has sometimes lagged when moving in and out of good LTE coverage.

All of these features are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide displays you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to remember that orbital service is limited to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with options 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 lacks any recycled components. Garmin offers disposal schemes on recent purchases.

Price

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re without coverage.

The result is an even more remarkable outdoor device for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is very freeing to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the features. At least it isn’t dependent on your phone provider so works with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or hiking, but still wants to be locatable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very costly, LTE and satellite functions need ongoing subscription, limited Garmin Pay bank compatibility, voice features are slow, basic smartwatch functionality versus competing watches.
