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

The newest version of the top-tier Fenix adventure watch introduces a potentially lifesaving feature: no-phone messaging and emergency messaging via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding cutting-edge cellular technology, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier model and engineered to be the single gadget needed to venture almost anywhere and track every activity.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the standard Fenix 8.

You do get a significant functionality for your money, with industry-leading workout, movement and outdoor tracking. Its complete offline maps of the globe can seamlessly guide you return to the path if you get lost without a phone, and look excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, 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 despite the screen always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

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

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messages, calls and LiveTrack position tracking – so your friends or family can monitor you while engaged in running, biking or similar pursuits – along with emergency satellite SOS messaging.

Location updates and texts over orbital are then charged on top, with higher-tier plans offering various 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 evaluate the service.

After you have got it set up, you simply head out the door without your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you can make and take calls, dispatch texts and overall keep in touch with your family and companions.

When you text 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 app, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of personalizable pre-set responses you can use to expedite communication. Spoken recordings and calls work acceptably, although as with most smartwatches, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts whenever you begin an exercise, so they can track your real time location on a map. It’s great for following competition performance, but it primarily serves as a utility for someone you trust to be aware of your location in case an incident occurs. It has generally worked well, although the real location has occasionally been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are available on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is essential to remember that orbital coverage is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with services offered through the customer service portal. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re out of signal.

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

It is very liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the service. At least it isn’t dependent on your phone provider so functions with any make of smartphone and network.

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

Pros: LTE and orbital communication, super-bright OLED display, monitors everything with premier GPS, integrated torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: very costly, LTE and orbital features require monthly payment, restricted Garmin Pay financial support, voice capabilities are slow, limited smartwatch functionality versus competing watches.
