Recently got a Huawei E620 USB modem. The modem is detected

When I try to dial through wvdial, I keep getting the following error

Can someone please help me to get this thing started. I have checked and rechecked my password and username and they are correct.

Ok so I have sorted out the connection thanks to the guide referred to by Alexfish. Seems I needed to set correct permissions. However I am still unable to browse although the modem gets connected. Can someone pls help me getting this to work?

Hi
Can you try This

dmesg | grep -e "modem" -e "tty"

ls -al /dev/ttyU*


and post the results

Also check to see if the Modem Interface (ppp0) Shows up in the Network Tools

if not there

sudo adduser "YOURUSERNAME" dip
sudo adduser "YOURUSERNAME" dialout

Check with

Code

id
