I noticed today the first time, that the SMS app do not want / do not allow me to send a sms to a number that is one digit longer as usual. Without the country prefix 12 instead 11 digits. The send button is deactivated and I can not type any text. A test with the manually typed in number shows that behaviour. [Provider in DE / SFOS 4.5.0.25].
Anyone seeing this? What controls this?
