What is Legal Cell Phone?

How to know if the cell phone’s IMEI is original or cloned
Anatel’s IMEI query portal only shows whether the cell phone is registered on the block list, but does not inform details such as model or manufacturer. Therefore, the alternative is to check the serial number on the IMEI checker website.
Some IMEI checkers options are imei.info and IMEI24🇧🇷 These sites allow you to check device model and manufacturer information that was originally assigned to the serial number. If the system returns a cell phone different from the one you have in hand, there are great chances that it is a cloned, tampered or pirated cell phone.
There are IMEI checkers that also check whether the cell phone’s serial number is on a blacklist, but in some cases they charge for the query and are not always reliable.
What is an IMEI blacklist
A blacklist or IMEI blacklist is a database used by operators to block irregular cell phones on their mobile phone networks. Equipment on this list is often devices that have been stolen, lost, tampered with, or cloned.
If the IMEI code is registered in this blacklist, the cell phone will not be able to authenticate with the telephone operator’s network. Thus, the device has no signal and is prevented from making or receiving calls, exchanging SMS and using mobile internet.
Are IMEI checkers reliable?

Anatel’s own portal informs the reason for the impediment, whether due to loss, robbery, theft, pirated cell phone or irregular device.
Can I find out who owns the cell phone by the IMEI?
It is not possible to identify the owner of a cell phone and his personal data just by IMEI code🇧🇷 Mobile operators are able to associate which lines used the device, but for security reasons, this information is only made available if there is a legal request.
Is it possible to unlock the IMEI of the cell phone?
