 //1.获取短信管理器 
 smsmanager sm = smsmanager.getdefault(); 
  
 //2.切割短信，把长短信分成若干个小短信 
 arraylist<string> smss = sm.dividemessage(content);//an arraylist of strings that, in order, comprise the original message 
  
 //3.for循环把集合中所有短信全部发出去 
 for (string string : smss) { 
  
  sm.sendtextmessage(phone, null, string, null, null);//send a text based sms. 
 } 
 }
