I'm pretty sure all of you don't read Wendigo's article and making random post
If you read that, then you will know that you can track your lost Android phone even if the thief changes the sim card, as long as the phone is switched on and you had registered gmail account there. But you will totally lose it if the thief does factory data reset.
as i told you earlier i have already read that article. But my phone is switched off and maybe my simcards are also taken out from phone. Which mean i can't trace any of them. I have strong pattern and fingerprint lock if he switches the phone on. So he have to factory reset everything if he wants to get into my phone which means everything on my phone is gone(all data/google accounts).
That's why i need someone who can trace it out with IMEI number.
Sorry, but that post didn't belong to you, I was talking for those who giving advice without read the article. Anw seems you don't have any important data on your phone then, since you have already known that there is a possibility all of your data is erased by thief and you still want to track it. Well, good luck mate.
