SMS to Email 效果
唔，最早的想法是：学校离家较远所以有两张SIM卡，而且由于资费原因只能分别在两地使用，想通过互联网代理，使得可以在一地同时使用两张卡..
最早想到的是使用闲置低端安卓机，后来发现手头闲置的一张华为数据卡（EC1261）可以利用，遂试着捣鼓出一个这玩意..
本文实现：
- 将所收短信转发至指定 E-mail
- 挂断来电并回复短信，同时发送 E-mail 提醒
虽然还不能接打电话，但至少接收各种验证短信不再麻烦了呢 
设备
闲置 华为数据卡 EC1261 一张
装 ubuntu 的 Cubieboard 一块
这张上网卡除了上网，收发短信也是可以的：流量提醒就是用短信实现的（所以总是一条条地接收）；带了个 2.5mm 耳机插口，应该是用来打电话的，虽然电信给的软件不带此功能。
其他型号的华为上网卡应该类似
安装
Windows: 插入装好驱动就成，华为上网卡用串口和 PC 通讯，插入后设备管理器中可见串口号（COMXX）。
Linux: 以前在 ubuntu 10.10 试过插上就能用。在刷了官网上下的 ubuntu 镜像的 Cubieboard 上，貌似装了 usb_modeswitch 才正常。若自行编译内核，需确保勾选usb_wwanoption模块。会看见类似/dev/ttyUSB0的设备出现。
脚本设计运行于 Linux，依赖 Python 2 和 pySerial，发邮件需装 sendmail 。
apt-get install python-serial sendmail usb-modeswitch
通讯
关于如何“操作”上网卡，这个是关键呢，感谢这篇文章给了我线索，搜索关键词 HUAWEI CDMA Datacard Modem AT Command Interface Specification 即可，PDF 里有详细说明。
根据说明写了段程序，完成标题所述功能：hw_smsd.py
（注意下读写串口可能需要 root 权限）

还比较简陋，但运行了几天没问题，就发上来～怎么说也算留个思路吧。
改进
记得刚才说的，这张上网卡有带一个 2.5mm 插口么，
和 Cubieboard 的 Line-In, 耳机口 相连，再装个 Asterisk 配置一下，一个自己的 SIP 网络电话就架成了～
不过目前来说，我对这功能需求并不迫切呢..
