The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

This most recent iteration of Garmin's flagship Fenix outdoor watch introduces a life-saving capability: no-phone messaging and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an available advanced microLED screen in a special edition. It is Garmin's top device and designed to be the only tool needed to venture almost anywhere and track all your movements.

This makes it an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the standard Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, movement and outdoor monitoring. The full offline mapping of the world can automatically direct you return to the path if you lose your way without a phone, and appear excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your mobile carrier, as with other wearables. However in contrast to competing satellite-enabled devices, SOS messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE text and voice messages, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while engaged in jogging, biking or comparable activities – plus emergency satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with higher-tier subscriptions including various allowances of orbital use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have completed setup, you simply venture outside minus 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 overall stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using text or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can send to speed things up. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to chosen contacts every time you begin an exercise, so they can track your live position on a map. It’s excellent for monitoring race performance, but it primarily serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned effectively, although the real location has occasionally been delayed when moving in and out of strong LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

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

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin offers recycling schemes on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without coverage.

Outcome is an increasingly remarkable outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very freeing to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. At least it is not reliant on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or hiking, but nevertheless wants to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: extremely expensive, LTE and orbital functions require monthly payment, restricted Garmin Pay financial compatibility, speech features are slow, limited smartwatch features versus Apple/Google/Samsung watches.
