I’m thinking of paying for Mullvad, but I don’t want to waste my money if I won’t be able to use it. My ISP blocks Tor (at least that is the conclusion I have come to - I can only connect via a bridge). Is there anything I can do to make sure I will be able to use Mullvad before I end up paying for it?
Mullvad has a 30-day money back guarantee.
Apart from that, some payment methods (like crypto) allow transmitting arbitrary amounts. At least, paying for years in advance works without issue. You could pay a few cents and try it out, but be mindful of fees.
