The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

This newest model of the flagship Fenix outdoor timepiece brings a life-saving capability: no-phone messaging and emergency messaging via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, plus an available state-of-the-art microLED display in a limited edition. This is Garmin's top device and engineered to be the only tool needed to venture virtually any location and monitor every activity.

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 reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, movement and adventure monitoring. The full offline mapping of the world can seamlessly direct you return to the trail if you get lost absent a phone, and look great on the large, sharp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life even with the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your phone provider, as with other wearables. But in contrast to competing satellite-enabled devices, SOS communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while out jogging, cycling or similar activities – plus SOS orbital SOS messaging.

Location updates and texts via orbital are then billed on top, with more expensive plans including different allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the service.

After you have completed setup, you just venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your relatives and friends.

When you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using text or voice messages, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of personalizable canned replies you can use to expedite communication. Spoken messages and calls perform OK, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to automatically transmit a URL to selected contacts whenever you start an exercise, so they can track your live position on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has typically worked well, though the actual location has sometimes been delayed when moving in and out of strong LTE coverage.

These features are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to find the line of sight 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 safety feature, however it is important to note that orbital service is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered through the support portal. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides disposal schemes on new purchases.

Cost

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

This is very freeing to be outdoors without a phone, but that capability carries quite a cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and network.

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

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and satellite functions require ongoing subscription, limited Garmin Pay bank support, voice features are slow, limited wearable features compared with competing watches.
