??????
The first explanation would mean two-way communication, but you say there is none ;
The second explanation would mean you have no way to test in the field, only at home/office ;
So, what is the third, correct, explanation I have been to dumb to understand ?? blush

confused Or does "end-to-end" applies to the unit only (from pushbutton to antenna), not the entire system, satellite and Geos response center included ????


End-to-end refers to the entire system. You have to be able to either check the web site or be able to check with one of the contacts that would receive a text message (which could also be yourself). The whole point of conducting a self-test is to do it before you go, not once you are in the field. Self-test is to ensure everything is working at a point in time that you can either repair or replace before it is critical. It provides confidence that the device will work when you need it to. Once you are already in the field it's too late, there's nothing to be done about it at that point.
