I like the opportunities this card is offering and the calling plan is good.
It works just fine.
The only thing for me which I struggled with was that the activation mail came after more than one hour after I purchuased it. That was not so good, that this fact was not told in advance. So I had to use up all my mobile limets in order to check and activate the e sim card.
The process to activate the card was well discribed and easy.
When you write it down, that the mail needs a bit of time to arrive I would have given all the stars.
