求解Tiny6410使用华为E1550进行3G拨号出现的莫名问题

（好吧，问题已经解决了，原来是我的卡欠费了～～）

上半年产的板子，固件是新刷的～～固件来自http://www.aiothome.net/read.php?tid-16184.html

可是在使用华为E1550进行拨号时出现问题了，不太清楚是什么原因造成的，下面附上错误提示信息，
望各位论坛里的大神们给分析分析，指条明路啊～～～

首先输入命令：3g-ppp /etc/3g-modem/12d1.1446.12d1.1001

            【前面的信息应该没什么大问题，关键是最后我字体加粗的那一快，没整明白是啥意思】

[root@FriendlyARM /etc]# 3g-ppp /etc/3g-modem/12d1.1446.12d1.1001

然后输入命令：call-ppp wcdma

[root@FriendlyARM /etc]# call-ppp wcdma
[root@FriendlyARM /etc]# rm: can't remove '/var/run/ppp0.pid': No such file or directory
rm: can't remove '/var/run/ppp0-ok': No such file or directory

这是/var/run目录的内容，没拨号成功

[root@FriendlyARM /etc]# ls /var/run/
fa-network-service.pid             inetd.pid               syslogd.pid             utmp

不明白是怎么回事，于是，使用最原始的pppd来进行拨号，
可是也没有成功，说是调制解调器挂断，连接终止了～～

                     【前面也是没有问题，也是在最后出现了问题，我用加粗表示出来了】

[root@FriendlyARM /etc]# pppd call wcdma

求各位大神帮帮忙，帮我看看是什么原因导致的这个问题，在下感激不尽啊～～～
