Can't find your phone? Are you all alone (poor thing) and don't have anyone to call it for you? Then use PHONE FINDER.
This happened to me once (poor thing) - and I had to search the internet and find a site that would send a free text message. Unfortunately, the text message notification on my phone is just a sing "DING" - so multiple texts were needed before I located my phone. Phone Finder actually calls you, allowing it to ring multiple times so you can find the little sucker.
