I am trying to run internet via HUAWEI E3372 on Debian. It worked on Windows but did not work on Debian.The error is this:

ATDT*99#
ERROR
--> Invalid dial command.
wvdial: utils/wvtask.cc:303: static int WvTaskMan::yield(int): Assertion
*current_task->stack_magic == WVTASK_MAGIC' failed.
Aborted

Here you are the issue info:

wvdial.conf

UPDATE

The configuration worked and internet got present actually. It was empty resolve.conf simlink so I copied /etc/ppp/resolve.conf one and it worked.

Anyway the error still remains and I would like to get rid of it.

Also note that I am doing all with Network Manager service disabled.
