Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Texting

The most recent model of the premium Fenix adventure watch includes a potentially lifesaving feature: no-phone messaging and emergency messaging via 4G LTE or satellite links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new mobile technology, along with an available state-of-the-art microLED screen in a special edition. It is Garmin's premier device and designed to be the only gadget required to venture virtually anywhere and track every activity.

That positions it as an extremely expensive option, priced from £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 variant with microLED screen – nearly twice the price of the regular Fenix 8.

You do receive a lot of functionality for your money, with industry-leading workout, movement and adventure tracking. The complete offline mapping of the world can seamlessly guide you back to the path if you lose your way absent a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the smaller 43mm version found in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your phone carrier, like other wearables. But in contrast to competing satellite-enabled devices, SOS messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, calls and LiveTrack position sharing – so your contacts or loved ones can monitor you while out jogging, biking or similar pursuits – plus SOS orbital SOS messaging.

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

After you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and generally keep in touch with your family and companions.

When you message someone, Garmin sends 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 communicate reciprocally using text or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of customisable pre-set replies you can send to speed things up. Spoken recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a link to chosen contacts whenever you start an exercise, so they can follow your live location on a map. It’s excellent for monitoring competition progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case something happens. It has typically worked effectively, though the actual position has sometimes lagged when moving in and out of good LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and SOS 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 important to note that orbital coverage is limited to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the support site. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling schemes on recent purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable outdoor device for those that want to be phone-free. If you wish to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to provide the service. At least it isn’t reliant on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED display, monitors everything with premier GPS, built-in torch, phone 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: extremely costly, LTE and orbital functions require monthly subscription, limited Garmin Pay bank compatibility, voice capabilities are sluggish, limited wearable features compared with competing watches.
