The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Texting

This latest model of Garmin's flagship Fenix outdoor watch includes a potentially lifesaving capability: no-phone communication and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier device and engineered to be the single gadget needed to explore almost anywhere and track all your movements.

That makes it an extremely pricey proposition, 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 display – almost double the cost of the regular Fenix 8.

You do receive a significant features for your money, with best-in-class workout, activity and outdoor monitoring. Its complete offline mapping of the world can seamlessly direct you back to the path if you lose your way without a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan tied to your phone carrier, as with other smartwatches. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, biking or similar activities – plus SOS orbital SOS alerts.

Location updates and messages over satellite are then billed additionally, with more expensive subscriptions offering various allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you just head out outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can place and receive calls, send texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally using typed or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a set of customisable pre-set replies you can send to speed things up. Voice messages and calls work OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own transmit a URL to chosen contacts whenever you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring race performance, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, though the actual position has sometimes been delayed when moving in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance displays 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 unexpectedly easy to use and could be a vital lifeline, though it is essential to remember that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with services offered through the support portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides disposal programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor tool for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is very liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone carrier so works with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or hiking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, tracks everything with premier GPS, built-in torch, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital features require ongoing payment, limited Garmin Pay bank support, voice capabilities are sluggish, basic wearable functionality compared with Apple/Google/Samsung watches.
