I lose my phone and i want that
If excite any idea for find my phone
You had android phone or Apple?
If the phone has no SIM, unless someone picks it up, turns it on and connects to a wifi spot so it has access to the internet (but does not log you out) AND you already had setup a phone-locator app, and you are able to access the app at that exact time in order to find it, then your phone is gone.
Unless you get lucky and someone returns it or hands it to a lost and found Dept or they informed police about it. But that of course would depend on where you lost it.
