There's this list to be checked, although it seem to be no longer maintained: https://docs.google.com/spreadsheets/d/1DRbTeMCzb4UeXI0YlAzBxMc2u2i0cN_17Ql6eMngK6E/edit#gid=0
Also you can check TenX (afaik they work in Asia) and AdvCash (they may have started selling outside Europe too, but I am not sure).
