SIMSme offers all the features that you have come to expect from a modern and advanced messaging app – and much more:

Your data remains YOUR data. Messages are encrypted on the sender’s device and can only be decrypted on the recipient’s device. Even we can’t view your message when you chat and message with your contacts.

Starting immediately, you can also send files with a size of up to 10 MB in SIMSme. Simply select the file via the “Open” menu in other apps and send it with SIMSme, or select a file from diverse storage locations, e.g. iCloud Drive, Google Drive, Microsoft OneDrive or Dropbox, via the “+” symbol in Chat
Using SIMSme, you can automatically destroy your sent messages so that the recipient can only view it for a limited time.

Send voicemail in your chat without the fear of eavesdropping. That way, your hands are always free when messaging.

SIMSme’s servers are located in Germany and will stay there. Of course, this also means that your data will be handled in accordance with German Data Protection Guidelines!

Sehr gute Alternative!


SIMSme biete alle nötigen Funktionen für einen guten Messenger. Sehr zu empfehlen.
Leider habe ich nur einen nicht ganz so kleinen Bug gehabt.
Ich hatte bei mir (iPhone X, iOS 11.4) die Funktionen „Passwort beim Start abfragen“ und „TouchID verwenden“ aktiviert (probehalber).
Leider ist SIMSme dann bei jedem Start direkt wieder abgestürzt. Nur das erneute installieren der App konnte den Fehler beheben.
Ansonsten bin ich sehr zufrieden :)

Eine sehr gute Alternative


Schade ist nur das es zu Wenige gibt die von WhatsApp zu SIMSme wechseln wollen nur weil sie zu bequem dazu sind.
Ich versuche ständig Personen darauf aufmerksam zu machen, aber die Wenigstens bis gar keiner wechselt.
Ein Bekannter hat gewechselt, nur er benutzt sie nicht.
Das ist sehr schade für mich.
Anscheinend ist es den Meisten egal was mit den Daten passiert.

Eine echte Alternative


Wenn das alles stimmt was die deutsche Post verspricht ist der Messenger eine echte Alternative zu anderen Messengern. Zusätzlich bietet die App mehr Funktionen als u.a. WhatsApp. Leider verwenden es momentan zu wenige Leute.
