我正在使用pppvia wvdial，脚本看起来像这样（注释行已被删除）：
[Dialer t-mobile]
New PPPD = yes
Phone = *99#
Modem = /dev/ttyUSB0
Modem Type = USB Modem
Baud = 460800
ISDN = 0
Username = “blank”
Password = “blank”
Init1 = ATZ
Init2 = AT+CGDCONT=1,"IP","internet"
Stupid mode = 1
Auto DNS = yes
当我wvdial t-mobile让它表现得像可以工作时：
sudo wvdial t-mobile
--> Ignoring malformed input line: "; [Dialer Defaults]"
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: AT+CGDCONT=1,"IP","internet"
AT+CGDCONT=1,"IP","internet"
OK
--> Modem initialized.
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#
CONNECT
--> Carrier detected. Starting PPP immediately.

--> pppd: ▒▒v▒▒o
--> secondary DNS address 213.158.199.5
--> pppd: ▒▒v▒▒o
ifconfig对于此接口：
ppp0 Link encap:Point-to-Point Protocol
inet addr:100.88.98.150 P-t-P:10.64.64.64 Mask:255.255.255.255

因此脚本似乎可以运行，但实际上却不能... 无论如何都无法连接互联网... 无法 ping 通（甚至无法 ip 地址），HTTP 服务器也没有响应100.88.98.150。
知道可能是什么问题吗？
顺便说一句，10.*和100.*都是本地/保留地址...所以我不太明白...也许我的卡上没有足够的钱？我没有办法检查。
