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

TRUE END-TO-END ENCRYPTION
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, the operators, cannot view your messages on our own servers.

FREE FOREVER
Save on fees compared to traditional SMS or other messengers.

MULTIMEDIA
Send photos, videos, contacts and locations - encrypted, of course!

NO EXTRA PHONE BOOK
SIMSme uses your phone/address book to connect you to your contacts. The phone numbers in your phone book are anonymised and compared to our user database in an encrypted manner. A connection is only established if we can find both your contact and yourself on our service. Contacts that have not yet signed up to use SIMSme will never be saved on our server. Guaranteed.

SERVERS LOCATED IN GERMANY
The SIMSme servers are located in Germany and will stay there. Of course, this also means that your data has to be handled in accordance with German Data Protection Guidelines!

SELF-DESTRUCTING MESSAGES
Using SIMSme, you can either specify an "expiration date" for your messages or only make your messages readable for a certain period of time. Our "self-destruction" feature serves to keep private matters truly private!

Download SIMSme now and stay up to date at all times – in both your professional and private lives.

Eine Backup-Funktion, mit der man sein Konto auf ein anderes Handy umziehen kann, wäre noch wünschenswert. Ansonsten eine gute App, die hoffentlich in Punkto Usability noch überarbeitet wird...
