SMS not working on the mini???

There are no current or recent reported outages. You can check status from the upper right corner of the explore.garmin.com web site. Or via this URL: https://status.inreach.garmin.com

From there, you can also subscribe to email status updates.

If the problem persists, call tech support. If you have not done so, try messages to different numbers. And, if possible, to people with different cell providers. In the past, there have problems which were unique to specific providers.

Recent SMS I sent took three months to show up at recipients devices, so give it some time.....

Do not depend on the inReach for life saving services.

Sending an SOS to GEOS and texting your mate Billy-Bob to come pick you up in his truck involve two totally different systems. Don't conflate the two

hi, could you solve it? same here with a gpsmap 66i. Also i can recieve sms from mapshare.

There are no recently reported SMS outages. Most of the persistent problems reported in the past were traced to issues with AT&T SMS handling. That is, AT&T getting in the way of messages with particular types of content. AFAIK, all of those were promptly resolved. But it did happen at least two different times, as AT&T made continuing changes.

If you are still having problems, call tech support.

Give it about three months.... They will eventually get there! (mine did)

Sent on the device or in the app means it got off the device. Lots of moving parts from there to the recipient. No way to determine delivery to the final recipient except by the recipient. You can check the inbox on your account at explore.garmin.com to see if it made it to the Garmin servers. That’s about it.
