How to find the lost mobile when no tracker app is installed? 3 weeks ago, I lost my Samsung Galaxy Ace Dduos 6082. 

I don't have any tracker applications or any "if lost" applications installed. I'm looking for some tracker. I have IMEI number and Gmail installed in that. 

Is there any way to find my lost Samsung Galaxy Ace S6082?
Have you heard of plan b ?


  Plan B is your last resort to find your missing phone. This is the
  first and only 'find my phone' app that you download AFTER you've
  already lost your phone. Having Lookout on your phone is the best way
  to protect your phone and find it fast, but use Plan B if you have
  already lost your phone and didn't have Lookout installed.

NOTE: Plan B only works with 2.0 - 2.3 versions of Android
