The Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

This newest version of the flagship Fenix outdoor watch brings a potentially lifesaving feature: no-phone messaging and SOS messaging via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an optional advanced microLED display in a limited edition. It is Garmin's top model and engineered to be the single gadget required to venture almost anywhere and track all your movements.

This makes it an very expensive option, priced from £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 screen – nearly double the price of the standard Fenix 8.

Users receive a significant functionality for your money, with industry-leading fitness, activity and outdoor monitoring. The complete offline mapping of the world can automatically guide you return to the trail if you lose your way absent a phone, and appear excellent on the large, sharp 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 big watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life despite the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service service rather than relying on a watch plan linked to your mobile carrier, like other wearables. But unlike competing satellite-enabled products, SOS communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in running, cycling or comparable activities – plus SOS satellite SOS messaging.

Check-ins and texts via orbital are then billed on top, with higher-tier subscriptions including different quotas of orbital usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally stay connected with your relatives and friends.

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

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable canned replies you can send to expedite communication. Spoken recordings and calls work acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s excellent for following competition progress, but it mostly serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned effectively, although the actual location has sometimes been delayed when moving in and out of good LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to remember that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the support site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. Garmin provides disposal programs on recent purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re without coverage.

The result is an increasingly impressive adventure tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. At least it isn’t dependent on your phone provider so works with any brand 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 trekking, but still wants to be locatable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, tracks everything with premier GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and satellite features require ongoing payment, limited Garmin Pay financial support, voice features are slow, basic wearable functionality versus competing watches.
