└─>USB driver for GSM and CDMA modems
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Say Y here if you have a GSM or CDMA modem that's connected to USB.

This driver also supports several PCMCIA cards which have a
built-in OHCI-USB adapter and an internally-connected GSM modem.
The USB bus on these cards is not accessible externally.

Supported devices include (some of?) those made by:
Option, Huawei, Audiovox, Novatel Wireless, or Anydata.

To compile this driver as a module, choose M here: the
module will be called option.

If this driver doesn't recognize your device,
it might be accessible via the FTDI_SIO driver.
