title: how to calculate the size of data transfered from Windows phone 7 to a REST WCF service over the internet?
body: <p>I need to calculate the size of the data transfered using mobile internet connection. and I am confused how to do it, can somebody please guide me to calculate the size based on my scenarios.</p>
  
  <p>My application is doing these functions.</p>
  
  <ul>
  <li>Reading geo location in standard formats and passing it to a wcf service.</li>
  <li>When our delivery man is pressing a button (could be any action) then again we are passing it to a wcf service</li>
  </ul>
  
  <p>So in simple words we are using internet and consuming WCF services. We are aiming to pass a string of maximum 500 characters, based on the message type. like if its a geo location then the string could be &lt; 30 characters if some action has been done like a button has been pressed it could be from 30 to 500 characters.</p>
  
  <p>Because we are using internet available on the sim and only 500 mb is allowed per month and we dont want to exceed this limit.</p>
  
  <p>So i need to calculate the size of the data transfered at one time to that webservice. Size interms of kilobytes etc  </p>
  
  <p>Thanks</p>
