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

This latest version of Garmin's premium Fenix outdoor timepiece includes a potentially lifesaving feature: phone-free messaging and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating new mobile tech, plus an optional advanced microLED screen in a special edition. It is Garmin's top device and engineered to be the single tool required to venture almost any location and track every activity.

This 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the standard Fenix 8.

You do receive a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. Its full offline maps of the world can automatically guide you back to the path if you lose your way without a phone, and look excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your mobile carrier, as with other wearables. But in contrast to Apple or Google's satellite-capable devices, SOS communication is not provided for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messages, call functionality 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 orbital SOS alerts.

Check-ins and texts via satellite are then billed 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 trial period so you can evaluate the service.

Once you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, send texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using typed or spoken communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to register for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can use to speed things up. Voice messages and calls perform OK, although as with most wearables, you’re not going to want to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to chosen contacts every time you begin an exercise, so they can track your live position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally worked well, though the actual position has occasionally been delayed when moving in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though it is important to remember that satellite service is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services available via the customer service portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling programs on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re without signal.

The result is an increasingly remarkable adventure device for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the features. At least it isn’t dependent on your phone provider so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED display, tracks everything with premier GPS, built-in torch, voice 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.

Drawbacks: very costly, LTE and orbital features need ongoing subscription, restricted Garmin Pay financial support, speech capabilities are sluggish, basic wearable features versus Apple/Google/Samsung watches.
