messenger plus sending pic to email?

No, you didn´t miss anything.

inReach® satellite communicators make it easy to send text messages from remote areas of the world by connecting to the Iridium satellite network, which provides 100% global coverage. When used with the Garmin Messenger app, the inReach Messenger Plus adds the ability to also send and receive photo and voice messages with other Garmin Messenger app users over the Iridium satellite network.¹ If you send a message to someone who does not have the Garmin Messenger app, they will receive an invite to the app so that they can view the message.

Photo and voice messages cannot be sent to email, inReach, or social addresses.

>>If you send a message to someone who does not have the Garmin Messenger app, they will receive an invite to the app so that they can view the message.<<

so how should we deliver this kind of invitation to someone who has not messenger?

There seem to be only possible to  address messenger accounts?

edit:

we thought a traveller could send some media information to his supervisor in the office somehow. Such supevisor certainly not have a messenger on his desk, he will have computer and phone

One don´t need a messenger, only the app. If you sent a pic to a phone number and the receipient has not the messenger app, he/she will get an sms " You have been sent a photo. Download the messenger app to view the photo" (incl. an app download link) (same for voice message).

Btw: there are up to1600 character messages possible with M+/Messenger app. If you sent a 1600 message for example to a mini 2 address, the message is splitted into11 parts for the mini 2 receipient (and each counts against his contingent or bill) and it will take time until all 11 parts have been received.

yep, we found this

meaning rather useless system for professional use. In professional world, there will be no recipient able to install anything on his phone, (.gov phones) so it is all just for fun use

for real use, we would need the links to be delivered by other means as well, not only to garmin highjacked phones

we thought, we might be able to deliver some data from the field by this like we did earlier with thuraya phones etc

OK , it was just short dream

I wake up this thread

I am brainstorming on this subject. What would be needed to get messages and forward them to some 'normal' destination?

OK, currently, the only recipient can be a highjacked phone which is unusable as .gov phones can not be used this way..

What would it need to have a destination phone and kind of forward messages to normal communication channels?

I am working on something (mostly for fun) to get the whole ting bridged into the matrix open source ecosystem. I think the way to do it (for media) is to set up android within a linux system, which can run android (waydroid). If you then have 1 garmin messenger account as a sort of gateway that all media files are sent to, you can quite easily extract the media from the linux computers file system. Then you need some sort of overlay to link the messages/media received to where they should be sent - and then it can be automatically forwarded to email based on a mapping on the host. Will post back when i get a bit further in getting this to work!

So yeah, i got it working. But understand it might be too "hacky" for corporate/.gov users.. But all you need is essentially a raspberry pi. Install waydroid which lets you run the Garmin messenger Android app natively on your raspberry pi. Then you either need to log in via your own garmin account, or create a separate relay account of sorts with another valid phone number. Then what i have done is to create a watcher script that runs constantly on the pi, and looks for new messages and media files to come in - and matches them to a subscription (a certain phone number matched to forwarding messages to a certain mail address or matrix webhook). I have the first versions working for relaying the media files into my matrix rooms - but will also work on a more general version that just relays the media files to an email account.
