Can you track mobile using IMEI number?
The IMEI (International Mobile Equipment Identity) number is
specific to the handset. The mobile number is associated with the
SIM card. If you swap a different SIM card into the mobile phone,
it will have a different mobile number but the same IMEI
number.
The mobile company will have a record of the IMEI of the handset
that used a particular mobile number for a particular call, and
your mobile provider has a record of the IMEI of any phone you
purchased from them, but you cannot in general trace the IMEI by
the mobile number.
