收發短信是oFono所支持的一項基本功能。用phonesim也可以模擬短信的收發。oFono本身不會保存短信，而是希望第三方plugin如sms history來把短信保存到sim卡或者SD卡上。
1. 啓動oFono並power on modem。
2. ./ofono/test/receive-sms 用來監聽是否有新的短信
3. 通過send-sms腳本可以發短信。比如
xxx@xxx:~/ofono/test$ ./send-sms 135xxxxxxxx "Hello World"
從oFono console log中可以看到短信發送的全過程。它會把短信encode成PDU格式，用AT+CMGS發送出去。你還可以設置短信delivery report來確認短信是否真正發送出去了。
