Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Texting

This latest iteration of the premium Fenix outdoor watch brings a life-saving capability: no-phone messaging and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating new cellular technology, along with an optional state-of-the-art microLED display in a limited edition. It is the brand's premier device and designed to be the single gadget required to venture almost any location and monitor every activity.

This 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 variant with microLED display – almost double the price of the standard Fenix 8.

You do get a significant features for your investment, with industry-leading workout, activity and adventure tracking. Its full offline maps of the world can automatically guide you return to the path if you lose your way without a phone, and look excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of smartwatch battery life even with the display always active, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone provider, as with other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, emergency communication is not included for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – along with emergency orbital SOS alerts.

Location updates and texts over satellite are then charged additionally, with higher-tier plans offering various quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

Once you have completed setup, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, send texts and overall keep in touch with your relatives and friends.

When you message someone, Garmin sends 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 text or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is sufficient to register for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can send to speed things up. Spoken recordings and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to chosen contacts every time you start an activity, so they can track your live location on a map. It’s excellent for monitoring race progress, but it primarily acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned effectively, although the real location has sometimes been delayed when moving in and out of good LTE coverage.

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

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is important to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with options offered through the support portal. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused components. Garmin offers recycling programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone provider so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED screen, tracks everything with best-in-class GPS, built-in flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: extremely expensive, LTE and satellite functions need ongoing payment, restricted Garmin Pay bank support, voice features are slow, limited wearable functionality compared with Apple/Google/Samsung watches.
