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

The latest model of Garmin's top-tier Fenix outdoor timepiece introduces a life-saving capability: no-phone communication and emergency messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, along with an optional advanced microLED screen in a special edition. It is Garmin's top model and designed to be the single tool required to venture virtually anywhere and track every activity.

This 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 edition with microLED display – almost double the cost of the standard Fenix 8.

You do get a significant features for your money, with industry-leading workout, movement and outdoor monitoring. Its complete offline maps of the world can automatically guide you back to the path if you get lost without a phone, and appear great on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription service instead of relying on a watch plan tied to your mobile carrier, like other smartwatches. However in contrast to Apple or Google's satellite-enabled products, emergency messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, biking or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive plans including various allowances of satellite use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the service.

After you have got it set up, you just venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message back and forth using typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can use to speed things up. Spoken recordings and calls work OK, though as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically send a URL to chosen contacts every time you start an exercise, so they can track your live position on a map. It’s great for following competition progress, but it primarily serves as a utility for someone you rely on to know your location in case an incident occurs. It has generally functioned effectively, although the actual location has sometimes lagged when transitioning in and out of good LTE signal.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays 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 crucial safety feature, though it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services available through the support portal. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides recycling 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 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 texting, calls and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without signal.

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it is not dependent on your phone provider so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, cycling or trekking, but still wants to be locatable and reachable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED display, monitors all activities with best-in-class GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and orbital functions need ongoing subscription, restricted Garmin Pay bank support, voice capabilities are slow, limited smartwatch features versus competing watches.
