Track you smartphone turned on, if SIM card in phone no, how can I track?
For example if the person is in development.
To track a smartphone enabled, if SIM card in phone no, how can I track ?
wifi is also turned off and SIM card removed from phone, you can track the location ?
I've learned that if you turn off the phone but leave the SIM card in the phone, then a cell can you track the location of a phone . I think if you remove the SIM card, disable wifi, but to turn the phone on, it really to track the location of a phone ?
If the SIM card is not in the device, but the cellular module is included - the phone can log in to the network and becomes known to the equipment operator. (The phone on the screen to show anything if there is no communication or show scale admission - no warranty).
Network without a SIM card possible emergency calls.
I think it's even a requirement of cellular standards.
You can check this is to pull the SIM card and try to call 112.
By itself, the cell phone is a radio transmitter and his work in communication networks can be detected by listening to the radio, and the location will be calculated according to the signal level at the base stations (so are the Search/Locator) or elangomats by radiation, for example, as shown in the film about Stirlitz.
