User reviews

Paket „EU 100 Minuten“ Anzeige funktioniert nicht

Die Anzeige der 100 EU Minuten funktioniert nicht, auch beim aufbrauchen zeigt es weiterhin „nur 0 benutzt“ an. Fehler besteht seit >1 Jahr. Danke

Werbelastig und kompliziert

Beim Wechsel von Themenbereichen wird unnötig Werbung aufgerufen.

Das Menü ist altertümlich gestaltet und unnötig komplex.

Wichtige Punkte wie aktuelles Guthaben gehören hervorgehoben.

Absolut brauchbare App...

Übersichtliche App mit allen wichtigen Funktionen. Aber das Design. 😖 Täuscht es mich oder sind mit dam neuen Logo die Farben der App noch schlimmer geworden? Bitte ändert das Design ...

Language

What is wrong with telecom company and german speaking countries that they only offer one language? Where is english?

Super

Funktionen sind ok, hat alle Infos ! 2oder mehrere Karten verwalten wäre schön.
