Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Texting

This newest iteration of the top-tier Fenix adventure watch introduces a potentially lifesaving feature: phone-free communication and SOS messaging using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile technology, along with an optional state-of-the-art microLED display in a special edition. It is the brand's top device and designed to be the only gadget needed to explore virtually anywhere and monitor all your movements.

This makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the price of the regular Fenix 8.

You do get a significant functionality for your money, with best-in-class fitness, activity and outdoor monitoring. The complete offline maps of the world can seamlessly guide you return to the trail if you lose your way without a phone, and appear great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size available in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the display always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service service rather than depending on a watch plan tied to your mobile carrier, like other wearables. However in contrast to competing satellite-capable products, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while engaged in running, biking or similar activities – along with SOS orbital SOS alerts.

Check-ins and texts over satellite are then charged additionally, with more expensive subscriptions including different allowances of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you just venture outside without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, dispatch texts and overall keep in touch with your relatives and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via text or spoken messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to expedite communication. Spoken recordings and calls perform acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can configure to on its own transmit a link to selected contacts every time you begin an exercise, so they can track your real time position on a map. It’s great for monitoring race progress, but it primarily serves as a utility for someone you rely on to know your location in case an incident occurs. It has typically functioned well, though the actual location has sometimes 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 orbital kicks in on the Fenix 8 Pro to transmit texts, position updates 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 unexpectedly easy to use and could be a crucial lifeline, however it is essential to note that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options available through the customer service portal. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling schemes on recent 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 takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re out of coverage.

The result is an even more remarkable adventure device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without requiring anything else.

This is very freeing to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial price 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 brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking 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.

Advantages: LTE and satellite communication, high-luminance OLED display, monitors all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: extremely costly, LTE and satellite functions need monthly subscription, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable functionality versus competing watches.
