Is Nexo card available worldwide?

Could you please clarify for me, is the Nexo card accessible and operable in all regions of the world? I'm interested in understanding its geographical availability, as I'm considering it as a potential financial tool. Could there be any limitations or exclusions in certain countries or regions? It would be helpful to know if there are any specific requirements or restrictions that might apply to certain users. Additionally, I'm curious about the potential fees or charges that might be associated with using the Nexo card internationally. Could you provide some insight into these matters?
