Am getting the error " Bad Request HTTP Error 400"

[tharini]

Whenever i run my SMS API code,am getting the error " Bad Request HTTP Error 400.The Request is badly formed". When i store a particular mobile number in database and send sms to that mobile no.,the msg is sent successfully only for few times after that am getting the above mentioned error msg.

I dont understand why the msg is not sent to the same mobile number few days after storing in databese...I have given my sms code below.Can anyone give me some better suggestions?
