After covering all basic questions, I will now explain what is legit and what is a scam. Most of the tools that claims to bypass or unlock iCloud just by paying and entering imei or serial number is 99% scam. An exploit or ios bug is a must to bypass icloud. Most of the legit tools will ask you to plug your device into a computer. Any tool that claims to have support for A12 and newer devices is 99% scam. There is currently no known exploit for A12 and newer devices and on newer iOS versions, there is no bug that can be used to bypass icloud. Any tool that can fully remove icloud on cellular devices is most likely a scam either. Most of the legit tools will require an A11 or older device to be jailbroken or to be on DFU mode beforehand.
