No it has not.
Trials have been done, not the same thing
End of...... Simples
Since neither you nor JohnD have come up with an example of where UBI has been actually tried, I can take it that it has not.
Another strawman
I am not arguing on the amount.
I am saying you have given me an example of what you claim is universal income, which does not meet the criteria for universal income -as determined by the quote you include in your post.
Criteria as posted by you:
It is supposed to cover the socio-cultural subsistence minimum
If you can show that by some miracle, a dividend whose amount is set by oil revenue prices, IE market forces, can be deemed to match 'socio-economic minimum' -then you have a case.
Until then you don't.
