The terminal device must be unlocked before using the SIM card of other carriers. The user can obtain the unlock code from the operator after the contract expires or in advance, and then enter the unlock code on the terminal device. If the unlock code input by the user is consistent with the unlock code generated or generated by the local device, the terminal The device prompts that the unlocking is successful, otherwise the unlocking fails. In order to prevent malicious brute force cracking, if the number of unlock failures exceeds the set value, the terminal device will be permanently locked, the unlock code cannot be continued, and only the operator's SIM card can be used.
