I do use boon. But it’s gonna be 1,49 in a month (my free year is over)
Due to PSD2 boon isn’t allowed to charge for top ups by credit card. So they decided to increase their monthly fee to 1,49€.
Nevertheless, boon is probably just a stopgap for most people. Apple users appreciate a hassle-free experience, so being dependent on a prepaid card rather than at least a debit card is anything but great.
