These people are scammers, they intentionally mislead you into thinking you have to buy credits separately making you think it's a single transaction because after all they didn't charge your card directly. After they ad on a contract you never get the chance to agree to and begin fraudulently billing your card. there's a reason they have comments disabled on their YouTube videos because of all the people who have been defrauded. They steal your money and then smugly inform you they won't be returning it. My charge-back says otherwise :D They're based in Switzerland for a reason and don't even use their real company's name of "Alohi". Avoid at all costs.

fax nummer in Deutschland nicht erhältlich, daher nur Basis Tarif möglich. Nach mehreren Nachfragen wurde mein account von Alohi geblockt. Das eingezahlte Geld ist für mich daher verloren. Keine Kontaktaufnahme zu Faxplus möglich. Käuferschutz über Paypal abgelehnt.
Ich kann nur unbedingt von dem Produkt abraten.
