Sending SMS abroad USA, Europa and Australia?

Call tech support. The more people who report an issue, the more likely it is to be addressed.

There have been partial outages (SMS delayed) almost every day since July 28. This may or may not contribute to the symptoms you see.

In general, SMS delivery depends on third-party SMS gateways in the destination area. With regard to South America specifically, I have seen several forum posts reporting continuing issues. Only tech support can tell you whether the issue is a temporary outage (for example, a technical problem with the gateway in your area), a permanent restriction (for example, no suitable gateway is available in your area), or something else (such as a problem with a particular cellular network provider). 

Thank you for your quickly reply. I put in contact already with tech support; the situation its not new for them; but based on other users here in Chili SMS never worked... So your advise about 'no suitable gateway is available in your area' seems to be the problem.

I made a test sending from Chili to France and Spain, and SMS arrived fine. I got the delivery phone numbers; they should be from those third parties companies you mentioned; that third party company is missing here.

Tech support is not really clear at that point, they said the problem should be in the receptionner mobile co. any kind of restriction; but I made a test with 3 companies with several numbers...

Thanks!

The issue with the recipient's cell provider has to do with attempts by the provider to suppress SMS spam. This is usually related to the inclusion of link to the location map in the SMS message. Garmin uses shortened URLs for the map link. Some providers automatically assume that anything with a shortened URL is spam. This happens periodically with US providers, particularly (but not exclusively) AT&T. When this is the case, Garmin usually sorts it out rather quickly with the cell provider - at least in the US. I have no experience with overseas providers.

Unfortunately, you can't generalize from one cell provider to another. For example, when things are broken with AT&T in the US, SMS are delivered properly to Verizon subscribers and Sprint subscribers and so forth.

If the problem is spam detection, and if it's based on the shortened link to the map page, you can circumvent the restriction by removing the link. You can do that from your account at explore.garmin.com. On the Account tab, look in the lower right corner for the SMS Message Configuration section. Make sure that the box for "Include a link to an online map with my location" is NOT checked. The change takes effect immediately. No sync to the device is required. Unfortunately, the change applies to all SMS messages you send from the device.

MAAAAAAAAAAAAAAAAAAAAAAN!!!!

MASTEEEEeeeEEEeeeEER!!!

It worked! Thank you so much!!! No map-link, but at least the text. You saved Chili and Argentina man.

How can tech support not have considered this!!?

Dear 3855260 : Have you tryed to send one SMS to Argentinian carriers? Was it received? I live in Argentina and it only works thru Mapshare . Garmin´s useless support can not find a solution. I will be expecting your answer . Thank you Martin

Hi Martin; I have no one single contact from Argentina. This issue was discussed in the Chilean mountaineering federation fcb page, where few Argentinians told their same problems. If you are there and have at least the minimum 10 messages per month, compadre you can sacrify at least one and send it to yourself... I spent 7 out of 10 to figure this out... but due to COVID situation is not a drama at all. Éxito!

Dear Carlos: Next month I will activate it and will test . Tks for your suggestion .

Dear Carlos. I forgot to say that also never worked from Inreach test center too . So I am not having faith that it will be fixed

I believe Garmin is doing its job: they receive and 'send' the message; but due to the mobile company acting as intermediary and final deliverer; we are all depending of that final delivery. And it seems that the quality and resources of these companies is key for an effective service. You can call Garmin anytime, I did it, to check if a message was delivered; and they did; but they cannot ensure the third party job in this chain. I'm in contact with the companies of the numbers in my garmin phone book, but as a private user it is difficult to move something. Best

Dear Carlos : You are right . I also called Garmin and told me the same. However locoal carries have not a single clue what SMS form satellite is .

What is more I can not figure it out how my Bivystick (Garmin competitor ) works .

It is received with a random number but it is received .Inreach no.

So I think that we will have to trust only thru Mapshare (and have fatich that it never goes down or be hacked again
