Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The newest version of the top-tier Fenix adventure watch introduces a life-saving feature: phone-free messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, along with an optional advanced microLED display in a limited edition. This is the brand's top model and engineered to be the single tool needed to venture virtually any location and monitor every activity.

That positions it as an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the regular Fenix 8.

Users get a lot of features for your money, with best-in-class workout, activity and adventure tracking. Its full offline maps of the world can seamlessly guide you back to the path if you lose your way without a phone, and look great on the sizable, sharp and high-luminance touchscreen.

This 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. But the 47mm OLED model as tested does have an additional day of watch battery life despite the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your mobile carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, SOS messaging is not included for free.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and voice messaging, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in running, cycling or similar activities – along with emergency orbital SOS alerts.

Location updates and texts via satellite are then billed on top, with more expensive plans including various allowances of satellite usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message back and forth using typed or voice communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a phone number is sufficient to sign up for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a set of customisable canned replies you can use to speed things up. Spoken messages and calls perform acceptably, although as with the majority of wearables, 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 automatically transmit a URL to chosen contacts whenever you begin an activity, so they can follow your real time position on a map. It’s great for monitoring race performance, but it mostly acts as a utility for someone you trust to know your whereabouts in case something happens. It has generally worked well, though the real location has sometimes lagged when transitioning in and out of strong LTE signal.

These capabilities are available on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position 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 unexpectedly straightforward to use and could be a crucial safety feature, though it is important to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered through the customer service site. 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re out of signal.

The result is an even more impressive outdoor device for those that desire to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is quite freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the service. At least it is not dependent on your phone carrier so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be trackable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: very costly, LTE and orbital features require ongoing subscription, limited Garmin Pay financial compatibility, speech capabilities are slow, limited wearable functionality versus Apple/Google/Samsung watches.
