Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Messaging

This newest version of the premium Fenix outdoor timepiece includes a life-saving capability: no-phone communication and SOS alerts via 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an optional advanced microLED display in a limited edition. This is Garmin's top device and designed to be the single tool required to explore virtually any location and track every activity.

That makes it an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the price of the standard Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, activity and outdoor monitoring. Its complete offline maps of the globe can seamlessly direct you return to the path if you lose your way absent a phone, and look great on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your mobile carrier, as with other smartwatches. But unlike competing satellite-capable devices, emergency communication is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in running, cycling or similar activities – plus emergency satellite SOS alerts.

Check-ins and texts over satellite are then billed on top, with higher-tier plans including different allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have got it set up, you just head out outside without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and generally keep in touch with your family and friends.

When you text someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally using text or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is enough to register for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can send to speed things up. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to wish to use it for extended conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to automatically send a link to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for following competition performance, but it primarily serves as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically functioned well, though the actual location has occasionally been delayed when moving in and out of strong LTE signal.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is essential to note that orbital coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered through the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal schemes on recent purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re without signal.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outside without a phone, but that functionality comes at quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to enable the features. Fortunately it isn’t reliant on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED display, monitors everything with premier GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital features need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, limited smartwatch functionality compared with competing watches.
