Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

The latest model of the flagship Fenix outdoor watch brings a life-saving feature: phone-free communication and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new mobile technology, along with an optional advanced microLED display in a special edition. This is Garmin's premier model and designed to be the single gadget needed to explore virtually anywhere and monitor all your movements.

This positions it as an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the cost of the regular Fenix 8.

Users get a lot of functionality for your investment, with best-in-class fitness, movement and adventure tracking. The full offline mapping of the globe can seamlessly guide you return to the path if you lose your way absent a phone, and appear excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your phone carrier, as with other wearables. However in contrast to Apple or Google's satellite-capable products, emergency communication is not included for free.

Instead, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack position tracking – so your friends or family can monitor you while engaged in running, biking or similar activities – along with emergency satellite SOS messaging.

Location updates and messages over orbital are then charged on top, with more expensive plans including different allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, send texts and overall keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned responses you can send to speed things up. Voice messages and calls perform OK, though as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the quality is not fantastic.

LiveTrack is the most useful feature. You can configure to on its own send a URL to selected contacts every time you start an exercise, so they can track your live position on a map. It’s excellent for following race performance, but it primarily acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has generally functioned effectively, although the real position has occasionally been delayed when moving in and out of good LTE coverage.

All of these features are accessible on other Garmin watches if you bring 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 check-ins and SOS SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is important to note that orbital service is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered via the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin offers disposal programs 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 service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable adventure device for those that want to be unplugged. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to enable the service. At least it is not dependent on your phone carrier so works with any make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED screen, tracks everything with premier GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital features require monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, limited smartwatch functionality versus competing watches.
