Instead, ModemManager uses the following command to preconfigure the authentication settings to use before launching the connection: AT*EIAAUW=2,1,"username","password" The given username and password are given in the current charset encoding configured in the modem, which should be UTF-8 preferably. Now, the problem is that when special characters are required by the operator, e.g. in the username, the connection will not succeeed. E.g. for A1/Austria operator: AT*EIAAUW=2,1,"[email protected]","ppp" The issue may therefore be that we either don't pass the username/password encoded properly OR that the modem firmware actually has a bug in that command handling. Debug logs with MM 1.x are needed. Also, it would be a good idea to check whether the setting is READ properly after being written, with: AT*EIAAUR=2,1 Note that PPP on the TTY with those same username/password will actually work.
