The Garmin inReach Messenger Plus is a compact two-way satellite communicator that adds photo messages, 30-second voice messages and texts up to 1,600 characters to the established inReach SOS and location-sharing system. For remote hunting, its purpose is simple: maintain a communication path when the phone has no mobile coverage.
I used an older inReach on hunting trips in the New Zealand mountains, where normal phone service was unavailable. Being able to tell family in Australia that I was safe, share a location and retain an emergency contact option was genuinely valuable. This review uses that experience to assess the Messenger Plus workflow, while treating its newer photo and voice functions from Garmin’s current documentation rather than pretending they were present on my older unit.
Garmin inReach Messenger Plus Quick Verdict
- Best for: hunters, shooters and travellers spending meaningful time outside mobile coverage.
- Main advantage: two-way satellite text, photo and voice messaging plus interactive SOS in a 117 g device.
- Main limitation: an active subscription is required, and photo or voice messages depend on the Garmin Messenger phone app.
- Battery strength: up to 25 days at a 10-minute low-power messaging interval with full sky view.
- Important reality: satellite communication needs a clear enough view of the sky and is not instantaneous in every terrain or weather condition.
What the Messenger Plus Adds
The standard inReach Messenger already supports satellite text, check-in messages, location sharing and SOS. The Plus model adds media communication. When paired with the Garmin Messenger app on a compatible phone, it can send photos and voice messages through the Iridium satellite network. Longer text messages can provide more context than the 160-character format associated with older devices.
That extra context is useful in a genuine incident. A photo may show the terrain, weather, vehicle position or visible injury; a voice message can explain a complicated situation when typing is slow. These features do not replace the location and concise facts an emergency coordinator needs, but they can reduce ambiguity after an SOS has been acknowledged.

Battery Life Explained
The headline figure of 600 hours is correct only for a particular setting: a text message or location sent every 10 minutes in low-power messaging mode with adequate sky view. Garmin’s current support table translates that to up to 25 days. Performance mode at the same interval is rated to 110 hours, and a two-minute interval reduces battery life further.
| Use profile | Published maximum |
|---|---|
| 10-minute interval, low-power mode | 600 hours / 25 days |
| 10-minute interval, performance mode | 110 hours |
| 2-minute interval, low-power mode | 120 hours / 5 days |
| 2-minute interval, performance mode | 70 hours |
| Photo or voice messages | Up to 250 media messages per charge |
| Powered off | Up to one year |
Tree cover, steep terrain, cold conditions, frequent retries, tracking and phone charging can reduce those figures. I carry a small power bank on remote trips and would still charge the inReach before departure. The safety-charging function can give a depleted phone enough power to use the Messenger app, but it should be treated as a contingency rather than a general phone charger.
SOS and Emergency Communication
Triggering SOS opens a two-way exchange with Garmin Response, its continuously staffed international emergency coordination centre. The device sends location information, and the user can provide details through text or, with the Plus and app, photo and voice messages. The coordinator can continue the conversation and work with appropriate local responders.
An inReach is not a guarantee of immediate rescue. Dense canopy, a deep gully or an obstructed antenna can delay satellite contact, and response time depends on location, conditions and available services. Keep the device where it can see the sky, know how to start SOS from the unit without the phone, and carry the normal first-aid, navigation and shelter equipment needed to manage the wait.
Using It With and Without a Phone
The Messenger Plus is easiest to use with a charged smartphone because the Garmin Messenger app provides a familiar keyboard, contact view, group conversations, photos and voice recording. The device can automatically move compatible messages between Wi-Fi, mobile data and satellite, reducing unnecessary satellite use when another connection is available.
The phone should still be treated as a convenience rather than a single point of failure. Learn the device buttons, contact navigation, check-in function and SOS sequence. Keep the phone warm and protected, disable unnecessary battery drain and carry the correct USB-C cable. On a multi-day trip, send routine text check-ins from the most efficient available connection and reserve media messages for situations where the extra information has value.
Pairing and account changes are jobs for home, not the trailhead. Update firmware, sync contacts and verify that the intended recipients can reply before entering remote country. A successful two-way test is more meaningful than simply seeing a satellite icon.
Remote Hunting Workflow
- Activate and test the subscription before leaving home; do not discover an account problem in the field.
- Pair the Messenger app, download any required maps and update trusted contacts.
- Send a test message outdoors and make sure the recipient understands how to reply.
- Agree on check-in times and what a missed check-in means before the trip.
- Attach the unit high on the pack or clothing with the antenna facing the sky; keep it with the person if the pack may be separated.
- Keep messages concise when satellite conditions are poor, and reserve photos or voice for information that genuinely helps.
The device is most valuable when the communication plan is clear. A routine “all okay” check-in reassures family, but it should not encourage them to expect constant conversation. State the route, return time, vehicle location and escalation plan separately before departure.
Subscription and Ongoing Cost
An active satellite plan is required for inReach communication. Australian plan prices, activation charges, included media messages and suspension options have changed since the device launched, so the old article’s fixed price should not be used as a current buying figure. Check Garmin’s Australian consumer-plan page immediately before purchase and compare the annual cost, not only the hardware price.
Choose a plan around real behaviour: number of trips, tracking interval, routine texts and likely photo or voice use. A cheap plan can become expensive through overage charges, while a high plan wastes money if the unit sits unused. The device still needs to remain activated and tested when it is expected to serve as emergency equipment.
Messenger Plus vs Messenger vs Mini 2
| Device | Best fit | Main distinction |
|---|---|---|
| Messenger Plus | Communication-first remote trips | Photo, voice and longer text messages; up to 25 days at 10-minute low-power interval |
| Messenger | Lower-cost text and SOS | No photo or voice messaging; longer published tracking life in some profiles |
| Mini 2 | Users wanting more standalone navigation | On-device breadcrumb map, digital compass and navigation-focused controls |
The Messenger Plus is the strongest communication device of the three, but the Mini 2 remains attractive when navigation on the device matters more than media. Users who only need check-ins, text and SOS may find the standard Messenger sufficient. Do not pay for photo and voice unless the extra context is useful enough to justify the hardware and plan cost.
Limitations to Understand
- Photo and voice messaging require a compatible smartphone and the Garmin Messenger app.
- Satellite sends may take longer under canopy, beside cliffs or without a clear sky view.
- The small monochrome display is for messaging and status, not detailed mapping.
- Subscription and possible overage costs continue after the hardware purchase.
- Some countries regulate satellite communicators; check every destination, not only Australian rules.
Garmin inReach Messenger Plus Verdict
The inReach Messenger Plus is a meaningful upgrade for people who can use photo and voice context, not merely a cosmetic refresh. My experience with an older inReach showed why two-way satellite contact matters on a remote hunt. The Plus keeps that core value and makes the conversation more informative when a basic text is not enough.
It is best for remote users who will keep a subscription active, carry a phone and establish a proper communication plan. The standard Messenger remains the value choice for simple text and SOS, while the Mini 2 suits navigation-led users. For a hunter regularly outside mobile coverage, the Messenger Plus can justify its cost as safety equipment rather than entertainment.
Frequently Asked Questions
Can the Messenger Plus send photos without phone service?
Yes, with an active inReach plan, a compatible smartphone and the Garmin Messenger app. The photo is sent over the satellite network rather than the mobile network.
Does inReach SOS work without a phone?
Yes. SOS and basic communication controls are available on the device. The phone app makes detailed typing, photos and voice messages easier but should not be the only way the user knows how to request help.
Does an inReach work anywhere?
It uses the Iridium satellite network for broad global coverage, but local laws and an obstructed view of the sky can affect use. Always check the destination and test the device before the trip.
