The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

This newest model of the flagship Fenix outdoor watch brings a life-saving capability: no-phone messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile technology, plus an available state-of-the-art microLED display in a limited edition. It is Garmin's top model and engineered to be the single gadget required to explore almost any location and track all your movements.

That makes it an very pricey proposition, 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 edition with microLED screen – nearly twice the price of the regular Fenix 8.

Users get a lot of functionality for your investment, with best-in-class fitness, activity and outdoor tracking. Its complete offline maps of the globe can automatically guide you return to the path if you get lost absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a large watch for larger wrists. But the 47mm OLED version as tested boasts an additional day of watch battery life even with the display always active, lasting a solid eight to nine days between charges.

No-Phone Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your phone provider, like other wearables. But unlike Apple or Google's satellite-enabled products, SOS communication is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive subscriptions including various quotas of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

Once you have completed setup, you just venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message back and forth via text or spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned responses you can use to speed things up. Voice recordings and calls perform acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to chosen contacts every time you start an activity, so they can track your live position on a map. It’s excellent for following race performance, but it primarily acts as a tool for someone you trust to know your location in case an incident occurs. It has typically worked well, though the real position has occasionally been delayed when moving in and out of strong LTE signal.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to note that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically repairable with services available through the support site. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin provides 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 additional Garmin inReach subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to provide the service. At least it isn’t reliant on your phone provider so functions with all make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, cycling or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: very expensive, LTE and satellite features need monthly payment, limited Garmin Pay financial compatibility, voice features are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
