Qualcomm MSM6275 UMTS Vodafone card

Preferences

First of all make sure UMTS card is recognized by your system. You need PCMCIA support enabled in your kernel. If you compiled it as modules load the modules.

deathstar ~ # lspci

Nozomi – Accessing the card

Download und build the Nozomi kernel module. You can get it here.

cd nozomi_2.21alpha_060917
mkdir -p /lib/modules/KERNEL_VERSION/kernel/drivers/pci/hotplug (if it doesn't exists)
make
depmod
modprobe nozomi


After you succeeded in loading the nozomi module you should see something like this in dmesg:

nozomi 0000:04:00.0: Nozomi driver nozomi_tty
Initializing Nozomi driver 2.21alpha (build date: Jun 9 2008 15:00:29)
nozomi 0000:04:00.0: Version of card: 3
nozomi 0000:04:00.0: Initialization OK!


PPP Configuration

You have to supply the PIN to your SIM-card. There are two ways to accomplish this:

• Add “AT+CPIN=MY_SIM_PIN” to your chat script
• Use a little Perl script (for example if you use a PIN app)

#!/usr/bin/perl
 
use strict;
use warnings;
 
$SIG{ALRM} = sub { die("timeout: no response from modem $modem\n"); };
 
my §pin   = shift;
my $modem = '/dev/noz0';
 
open(MODEM, "+<", $modem) or die("Failed to open modem $modem: $!");
print(MODEM "AT+CPIN=\"$pin\"\n\r");
while (<MODEM>) {
    if (m/OK/) {
        close(MODEM);
        print("PIN accepted\n");
        exit(0);
    }
    if (m/ERROR/) {
        close(MODEM);
        print("PIN rejected\n");
        exit(1);
    }
}
 
exit(0);

Now it’s time to create the PPP config and chat scripts.

# IP addresses:
# - accept peers idea of our local address and set address peer as 10.0.0.1
# (any address would do, since IPCP gives 0.0.0.0 to it)
# - if you use the 10. network at home or something and pppd rejects it,
# change the address to something else
0.0.0.0:0.0.0.0
# pppd must not propose any IP address to the peer!

# Add the ppp interface as default route to the IP routing table

# ppp compression:
# ppp compression may be used between the phone and the pppd, but the
# serial connection is usually not the bottleneck in GPRS, so the
# compression is useless (and with some phones need to disabled before
# the LCP negotiations succeed).
