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

The latest iteration of Garmin's top-tier Fenix adventure timepiece includes a life-saving capability: phone-free communication and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile tech, along with an available advanced microLED display in a special edition. This is Garmin's premier model and designed to be the only gadget required to venture virtually any location and monitor all your movements.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the price of the regular Fenix 8.

Users receive a significant features for your money, with industry-leading fitness, activity and outdoor monitoring. The full offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and look excellent on the large, sharp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life even with the screen always active, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan linked to your phone carrier, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for free.

Instead, plans start at £7.99 or similar a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while engaged in jogging, biking or similar pursuits – plus emergency satellite SOS alerts.

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

After you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you are able to place and receive calls, send texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via text or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable pre-set responses you can send to expedite communication. Voice recordings and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following race performance, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned well, although the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

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

A guide shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered via the support site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any recycled materials. Garmin offers recycling programs on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the service. At least it isn’t reliant on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks all activities with premier GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital features need ongoing subscription, restricted Garmin Pay financial support, voice features are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
