收发短信是oFono所支持的一项基本功能。用phonesim也可以模拟短信的收发。oFono本身不会保存短信，而是希望第三方plugin如sms history来把短信保存到sim卡或者SD卡上。
1. 启动oFono并power on modem。
2. ./ofono/test/receive-sms 用来监听是否有新的短信
3. 通过send-sms脚本可以发短信。比如
xxx@xxx:~/ofono/test$ ./send-sms 135xxxxxxxx "Hello World"
从oFono console log中可以看到短信发送的全过程。它会把短信encode成PDU格式，用AT+CMGS发送出去。你还可以设置短信delivery report来确认短信是否真正发送出去了。
