I don't think I added any tariff, at least not on purpose. On the dashboard on the right where it lists my name, number, credit, etc it says this:

Aktueller Tarif: 9 Cent Einheitstarif

Tarif-Optionen:
Smart- & Allnet-Optionen: buchbar
Internet-Optionen: buchbar
Sprach- & SMS-Optionen: buchbar
Auslands-Optionen: buchbar
blau Kostenschutz: aktiv

The 100MB and 1GB options are both available (they cost less than the €14.81 credit the desktop site thinks I have). It's only the more expensive 3GB and 5GB plans that say I can't add them because my credit is low ("Ihr Guthaben reicht für die Optionsbuchung nicht aus").
