If your friend needs account+cards then Statrys, Airwallex (although I personally have some doubts about the latter ”“ nevertheless it works for some).
If your friend needs just cards then he can go for Soldo or Wallester (well, I am not sure whether Soldo currently onboards new clients, necessary to check UPDATE: just have checked, seems OK).
Statrys is our no.1 option, amazing advice. Airwallex is good, but it doesn't ship internationally. So you would need to ship it to your business address (registered agent). Our agent charges 200$ per parcel...no joke, be careful of asking when choosing an agent. 15 cards would be 3K
