GPRS over linux
This is how I configured my laptop to connect to the internet over GPRS. I own a Nokia E51 and I used the supplied USB cable to connect it to my laptop.
- On connecting my phone to the laptop via the USB cable, the phone prompts for mode. Pick PC Suite
- Run dmesg | tail to see if your phone has been detected.
pravin@pravin-pc:~$ dmesg |tail [ 7295.313526] usb 1-1: new full speed USB device using uhci_hcd and address 3 [ 7295.539647] usb 1-1: configuration #1 chosen from 1 choice [ 7295.552653] cdc_acm 1-1:1.10: ttyACM0: USB ACM device
- Run wvdialconf as root
- Modify `/etc/wvdial.conf`. For MTNL Mumbai GPRS service, my `wvdial.conf` looks like,
[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Modem Type = USB Modem ISDN = 0 Modem = /dev/ttyACM0 Baud = 460800 Phone = *99# Username = mtnl Password = mtnl123
- To connect to GPRS via the phone,
pravin@pravin-pc:~$ sudo wvdial --- WvDial: Internet dialer version 1.60 --- Cannot get information for serial port. --- Initializing modem. --- Sending: ATZ ATZ OK --- Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --- Modem initialized. --- Sending: ATDT*99# --- Waiting for carrier.
