The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This most recent iteration of the top-tier Fenix outdoor timepiece brings a life-saving feature: phone-free communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile tech, along with an available state-of-the-art microLED display in a limited edition. This is Garmin's top device and designed to be the only gadget needed to venture virtually any location and track every activity.

That positions it as an extremely expensive option, starting at £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 – almost double the cost of the standard Fenix 8.

Users receive a significant functionality for your investment, with best-in-class workout, movement and outdoor tracking. Its full offline maps of the globe can automatically guide you return to the path if you get lost absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your mobile provider, as with other smartwatches. However unlike Apple or Google's satellite-capable devices, SOS communication is not included for free.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out running, cycling or similar activities – along with emergency satellite SOS messaging.

Check-ins and texts over orbital are then billed on top, with higher-tier plans offering different allowances of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you are able to place and receive calls, send texts and overall keep in touch with your family and friends.

Whenever you message 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 message reciprocally using typed or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, just a mobile number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can use to speed things up. Spoken recordings and calls work acceptably, although as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can set it up to automatically transmit a URL to chosen contacts whenever you begin an exercise, so they can track your real time position on a map. It’s great for following competition performance, 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 real location has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are accessible on other Garmin watches if you carry 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 on-screen assistance shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is important to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with services available via the customer service site. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled components. Garmin offers recycling schemes on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans cost 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 texting, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without signal.

Outcome is an even more impressive adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to enable the features. At least it is not reliant on your phone carrier so works with any make of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, monitors all activities with premier GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and satellite features require monthly payment, limited Garmin Pay bank compatibility, speech capabilities are slow, basic wearable features versus competing watches.
