After installing CIS 4.0 it is not possible to establish a dialup connection using the XS W14 UMTS stick from 4G Systems. The dialup application (XSManager) shows an error “Limit reached” which is not documented. However it is still possible to establish a connection manually by using the (precreated) dialup connection in Windows.
