Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Texting

The latest version of the top-tier Fenix adventure timepiece brings a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED screen in a limited edition. This is the brand's premier device and engineered to be the single gadget required to explore almost any location and track every activity.

That makes it an extremely pricey 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 edition with microLED screen – almost twice the cost of the regular Fenix 8.

You do get a significant functionality for your investment, with best-in-class workout, movement and outdoor tracking. Its complete offline maps of the globe can seamlessly guide you return to the path if you lose your way absent a phone, and look great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your phone provider, like other smartwatches. But unlike competing satellite-capable products, emergency messaging is not provided for no cost.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in running, cycling or similar activities – along with SOS satellite SOS messaging.

Check-ins and messages over orbital are then billed additionally, with more expensive plans offering various quotas of orbital usage, climbing 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 just 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, send texts and overall keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally using typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It has a set of personalizable canned replies you can use to expedite communication. Spoken messages and calls perform OK, though as with most smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to automatically send a link to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you rely on to know your location in case an incident occurs. It has generally worked well, although the actual position has occasionally been delayed when moving in and out of good LTE signal.

These features are accessible on other Garmin devices 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 transmit texts, location check-ins and SOS SOS.

A guide displays you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to note that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered via the support portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal schemes on new 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).

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital communication, check-in and emergency SOS for when you’re without coverage.

Outcome is an even more impressive adventure tool for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin does so without needing anything else.

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

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, biking or hiking, but nevertheless desires to be locatable and reachable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED screen, tracks everything with premier GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: very costly, LTE and satellite features require ongoing payment, restricted Garmin Pay financial compatibility, voice features are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
