MC7700 / QCPDPP (empty user/pwd)

Hello,

does anybody know why the modem does not support this AT command using an empty user and pwd?
AT$QCPDPP=1,1,““,““
The modem itself returns with an error.

Using other settings with a user/pwd work.

E.g. web.vodafone.de with empty user/pwd does not work.

Do we make something wrong?

Thanks,
Johannes

Does data connection works if you put “vodafone” in both username and password fields instead of empty?

Thx

Thanks, I am aware that there are alternatives. But this is provider specific, I guess.
The question was: why does the modem itself does not like the at command?

Thanks,
Johannes

dummy / dummy as user/pwd works cause the provider (BELL, Canada) does not check it.
But the question remains: why does the modem does not accept the commands?
