A1 UMTS card under Linux – just works

January 27, 2008

I got my hand onto an A1 UMTS PC-CARD and I did some research on how to use it with Linux. At first just plug the card into your Notebook and look at the logfile (/var/log/syslog on Debian based distributions). On a Kubuntu Feisty and newer Kubuntu versions and Debian Etch it is supported as /dev/USBtty0. This worked for all Huwai based cards I got my hands on, also the USB versions.

You have now 2 possibilities:

The first is to use the official Linux drivers from Vodafone which work also for A1. Just go to http://www.vodafonebetavine.net/web/linux_drivers/

The advantage of the official closed source program is that it ships with a special program which shows you how good the reception is and if it’s using GPRS or UMTS – but it is closed source and maybe not available for your hardware and/or software platform. And specially it is an GUI application you may want the UMTS internet access for a display less router. The following describes how I did it on an Debian Etch based router.

First you need to install the pppd


# apt-get install ppp

Than you create following files with the shown content:


# cat > /etc/ppp/peers/a1
hide-password
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/a1"
debug
/dev/ttyUSB0
115200
defaultroute
noipdefault
user "[email protected]"
remotename a1
ipparam a1
replacedefaultroute
usepeerdns


# cat > /etc/ppp/pap-secrets
"[email protected]" a1 "www"


# cat > /etc/chatscripts/a1
# ispauth PAP
# abortstring
ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL
TONE' ABORT 'NO ANSWER' ABORT DELAYED
# modeminit
'' ATZ
'' AT+CGDCONT=1,"IP","A1.net"
# ispnumber
OK-AT-OK "ATDT*99***1#"
# ispconnect
CONNECT \d\c
# prelogin
# ispname
# isppassword
# postlogin

Now download this perl script and change the PIN code (line 11) to the one of your card. Don’t forget to set the executable flag. Now you can go online with


# ./setpin.pl
# pon a1

The setpin.pl script needs to be called once each time you inserted your UMTS card. This setup is mostly identical for the other Austrian UMTS provides as they sell the same Huwai cards A1 does, just some Init commands are different. It is easy to find the correct ones for your provider with Google.

  1. You can just use “gcom -d /dev/ttyUSB0” for the unlocking of your umts card, that also shows you the signal quality.

    you may download it at sourceforge, the name is contascattiumts

  4. […] UMTS card ( a Huawei E620 USB Modem) works without any problems. Take a look here for get it to work on the command line. I was not able to get it to work with the KNetworkManager. […]
