The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Texting

The most recent iteration of Garmin's flagship Fenix adventure watch brings a life-saving feature: no-phone messaging and emergency alerts via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding new cellular technology, plus an available advanced microLED display in a limited edition. It is the brand's top device and engineered to be the single tool needed to venture almost any location and monitor all your movements.

That positions it as an very pricey proposition, starting at £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 – almost twice the price of the regular Fenix 8.

You do get a significant functionality for your investment, with best-in-class workout, movement and outdoor tracking. The full offline maps of the globe can seamlessly guide you return to the path if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service service rather than depending on a watch plan tied to your mobile provider, as with other wearables. However in contrast to Apple or Google's satellite-capable products, emergency messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messages, call functionality and LiveTrack position sharing – so your friends or family can monitor you while engaged in jogging, cycling or similar activities – plus emergency satellite SOS alerts.

Check-ins and texts over orbital are then billed on top, with more expensive plans offering various allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the functionality.

Once you have completed setup, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally using typed or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a phone number is enough to register for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can use to speed things up. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a link to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s great for following race progress, but it mostly serves as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned effectively, although the actual position has sometimes been delayed when moving in and out of good LTE coverage.

These capabilities are accessible on other Garmin watches 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, location updates and emergency SOS.

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

Environmental Impact

The watch is typically repairable with services available through the customer service site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal schemes 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 cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without coverage.

The result is an even more remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you remotely while running out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

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

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors all activities with premier GPS, integrated torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features need monthly payment, limited Garmin Pay bank compatibility, speech features are slow, limited wearable features versus competing watches.
