使用 wvdial 撥號時出現“錯誤的初始化字元串”

我正在嘗試使用 wvdial 通過我的華為調製解調器 EM680 撥號。我的調製解調器正確打開，/dev/ttyUSB1但是當我執行 wvdial 時，我得到了這個：

# wvdial

為什麼這麼說bad init string.？我的/etc/wvdial.conf樣子是這樣的：

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","m2mstatic.apn"
Stupid Mode = yes
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Phone = *99#
Modem = /dev/ttyUSB1
Username = ;
Password = ;
Baud = 9600

這個 wvdial.conf 在下面的 ZTE 3G 調製解調器上工作：

[Dialer Defaults] 
Modem = /dev/ttyUSB0 
Init1 = ATZ 
Init3 = AT+CGDCONT=1,"IP","apnname" 
Phone = *99***1#
Username = user
Password = user
New PPPD = yes 
Stupid Mode = 1

你可以用我的 wvdial.conf 試試。

我遇到了同樣的問題，然後發現我的設備中沒有 SIM 卡。當我添加 SIM 卡時，它又可以工作了。

可能是 SIM 卡被鎖定了？我看過其他建議添加的文章：

AT+CPIN="0000"
