This tutorial explains the procedure how to connect and dial a Samsung U900.
Other CDMA phones / providers may be connected in the same way.
Connect the phone with an USB data-cable and then choose
*PC Studio* from the phone’s mode selection dialog.
(The phone also provides an option to set the default USB mode).
The other modes simply won’t work, since they’re obviously associated to other devices.
See the USB-modes of the Samsung U900 and their associated devices for clarification:
Media Player: Bus 006 Device 009: ID 04e8:5a0f Samsung Electronics Co., Ltd MTP Device PC Studio: Bus 006 Device 010: ID 04e8:6601 Samsung Electronics Co., Ltd Z100 Mobile Phone Mass Storage: Bus 006 Device 011: ID 05c6:1000 Qualcomm, Inc.
After connecting the phone you may verify the connection by checking the log:
root@x200:/etc# dmesg usb 6-1: new full speed USB device using uhci_hcd and address 10 usb 6-1: configuration #1 chosen from 1 choice cdc_acm 6-1:1.0: ttyACM0: USB ACM device
Insert the module (might already exist):
root@x200:/# modprobe usbserial
Open the wvdial.conf configuration file to edit it:
root@x200:/# nano /etc/wvdial.conf
My settings for the U900 in combination with FONIC (Germany):
[Dialer Defaults] New PPPD = yes Modem Type = USB Modem Modem = /dev/ttyACM0 Auto Reconnect = 0 Auto DNS = Yes Baud = 460800 ISDN = 0 Init1 = AT&F Init2 = AT+CFUN=1 Init3 = AT+CGDCONT=1,"IP","pinternet.interkom.de" Username=fonic Password=fonic Phone = *99#
Connect using wvdial
