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

This newest version of the top-tier Fenix adventure watch brings a potentially lifesaving capability: no-phone messaging and emergency alerts using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile technology, along with an available advanced microLED screen in a limited edition. This is the brand's top model and designed to be the only tool needed to venture almost any location and track every activity.

That positions it as an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, activity and outdoor tracking. The full offline mapping of the globe can seamlessly direct you return to the path if you lose your way absent a phone, and appear excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life even with the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

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

Instead, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messages, calls and LiveTrack location sharing – so your friends or family can monitor you while engaged in jogging, cycling or comparable pursuits – plus emergency orbital SOS alerts.

Location updates and texts over orbital are then billed additionally, with higher-tier subscriptions offering different allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the service.

After you have got it set up, you simply head out outside without your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, send texts and overall stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or voice messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable pre-set responses you can use to speed things up. Voice messages and calls perform acceptably, though as with the majority of smartwatches, you’re unlikely going to want to use it for extended conversations as the quality is not ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to chosen contacts every time you begin an exercise, so they can track your live location on a map. It’s great for monitoring race performance, but it primarily serves as a tool for someone you rely on to know your location in case something happens. It has typically functioned well, though the real location has sometimes lagged when moving in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance 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 unexpectedly easy to use and could be a crucial lifeline, though it is important to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options available through the customer service site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused components. Garmin provides disposal programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

It is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it is not dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be locatable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very expensive, LTE and satellite features need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
