首先，要有一台具备GPRS且带有modem功能的手机，以下以palm treo 650为例。

650是不带modem功能，要通过软件实现，下载 USB modem软件并安装在650上。该软件支持蓝牙和usb数据线两种模式!

下面首先看系统是否能检测到modem

sudo wvdialconf

Editing `/etc/wvdial.conf'.
            Scanning your serial ports for a modem.
            Modem Port Scan<*1>: S0 S1 S2 S3
            WvModem<*1>: Cannot get information for serial port.
            ttyACM0<*1>: ATQ0 V1 E1 -- OK
            ttyACM0<*1>: ATQ0 V1 E1 Z -- OK
            ttyACM0<*1>: ATQ0 V1 E1 S0=0 -- OK
            ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 -- OK
            ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 -- OK
            ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
            ttyACM0<*1>: Modem Identifier: ATI -- ENZO
            ttyACM0<*1>: Speed 4800: AT -- OK
            ttyACM0<*1>: Speed 9600: AT -- OK
            ttyACM0<*1>: Speed 19200: AT -- OK
            ttyACM0<*1>: Speed 38400: AT -- OK
            ttyACM0<*1>: Speed 57600: AT -- OK
            ttyACM0<*1>: Speed 115200: AT -- OK
            ttyACM0<*1>: Speed 230400: AT -- OK
            ttyACM0<*1>: Speed 460800: AT -- OK
            ttyACM0<*1>: Max speed is 460800; that should be safe.
            ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
            Found an USB modem on /dev/ttyACM0.
            Modem configuration written to /etc/wvdial.conf.
            ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

如果出现以下信息则能检测modem且将配置自动写入 /etc/wvdial.conf文件。你modem的设备文件为/dev/ttyACM0

由于配置文件为普通拨号而建立，所以不适合grps拨号，要作以下修改

[Dialer defaults]
            Init1 = at+cgdcont=1,"ip","cmwap"
            Modem Type = USB Modem
            ISDN = 0
            Phone = *99***1#
            Modem = /dev/ttyACM0
            Username = any
            Carrier Check = no
            Password = any
            Baud = 460800

保存后，使用wvdial拨号

sudo wvdial

使用超级用户操作，不然无法会提示设备忙，或更改用户权限。

到如已经成功啦!我们再来看看路由表

$ route
            Kernel IP routing table
            Destination Gateway Genmask Flags Metric Ref Use Iface
            10.216.91.0 * 255.255.255.255 UH 0 0 0 ppp0
            192.168.0.0 * 255.255.255.0 U 0 0 0 wlan0
            default 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0

因为我这里还连接到无线网络，所以默认网关是 192.168.0.1，如果只有GPRS拨号连接，则信息会是：

$ route
            Kernel IP routing table
            Destination Gateway Genmask Flags Metric Ref Use Iface
            10.216.91.0 * 255.255.255.255 UH 0 0 0 ppp0
            default 10.216.91.90 0.0.0.0 UG 0 0 0 ppp0

此时，只需设置代理即可以上网了代理为 10.0.0.172:80

由于移动限制了浏览器，必须要将浏览器头信息更改才能正常上网。不过已经可以上Q。MSN等聊天工具啦!!
