CQ: Getting an international radiogram out.

I’d like to get an international radiogram out to some family affected by weather, and don’t presently have the means to get on air and into a message net to do it. How can I do this? I’ve scoured the web and can’t seem to find any way to inject a message despite finding the Radio Relay website.

E: Cellular has been restored to the region. And I’ve managed to reach my family. Through all this, with your help and the help of the folks at Radio Relay Int’l, we’ve learned that there is no simple way to inject radiogram traffic internationally, nor does the US have a third-party traffic agreement with the destination country, which negates the system anyway.
