just remember, cuz here fines in EU, are like start from 25 000 euro, - when you lend the number to a client, make them sign a paper , that you lend them the number from X to Y date, and they will not use it to send unwanted messages - at least for europe its very important - this way , if someone complain in the country, you can go to a judge and show them the papers, and they will remove the fine
