title: Detect mobile device indoor (J2ME)
body: <p>I am trying to develop a mobile application using J2ME to detect the device indoor. As GPS is impossible to detect the mobile device indoor. So i am looking into using location base with cell id. Can anyone gives me some guidance on the approach of this?  </p>
  
  <p>opencellid.org provides a free source for detecting the mobile using cell id. Base on their API, it requires the input of the IMSI. But i am unable to retrieve the IMSI as it requires the manufacturer/operator domain permissions to do so.</p>
  
  <p>By the way, i am from Singapore, using Starhub as the service provider and testing my program on N97 mini. Not use it any of this information helps.</p>
  
  <p>Any other way around it as in beside the idea of using cell id?? Any help will be greatly appreciated... </p>
