       smssubmitpdu[] pdu2;          try{             pdu2 = smartmessagefactory.createconcattextmessage("my name barry allen. , fastest man alive. when child saw mother killed impossible. father went prison murder.", "+639234597676");             comm.sendmessages(pdu2);         }          catch (messageserviceerrorexception e500){             messagebox.show(e500.tostring(), "information", messageboxbuttons.ok, messageboxicon.exclamation);         }         catch (commexception e501){             messagebox.show(e501.tostring(), "information", messageboxbuttons.ok, messageboxicon.exclamation);         }
