Preanouncement - we will release end of next week or begin of week afterwards some optimizations of the SMS operation and iFrame for SMS. This will cover the following problems:

- User does not know that there is a time out and tries too late to enter the SMS code. A time bar with the elapsing time will be shown.

- Textual adaptations which could disturb the user experience in some constellations.

- More settings for the iFrame: see [https://github.com/SwisscomTrustServices/AIS/wiki/SAS-Documentation](https://github.com/SwisscomTrustServices/AIS/wiki/SAS-Documentation) 

- More providers for the SMS sending process which could lead to a better coverage of countries in the world

- Retry possibility for users if the SMS was not received
