Here’s how you use a Sierra Wireless 595U USB modem to connect to wireless Internet service with Sprint:
Insert the modem into the USB slot. lsusb should show:
Bus 001 Device 005: ID 1199:0120 Sierra Wireless, Inc.
modprobe usbserial vendor=0×1199 product=0×0120
You should see /dev/ttyUSB0, ttyUSB1, and ttyUSB2 appear. See also instructions for automating this with a similar card (modify vendor and product to above settings).
Now you will need to configure PPP for this. On Debian, run pppconfig. Your settings will be:
Phone number: #777
Username: firstname.lastname@example.org (replace 1234567890 with your data card’s “phone number”, no dashes)
Password: your sprint password
Speed (BPS): 921600 (use lower numbers such as 115200 if you have trouble with this)
Init string: ATZ
