Most cell phones have password features to restrict access to the owner's confidential information. Once we have set a password, we will always have to enter it until we remove its function in the settings. If you have forgotten the password for your phone or SIM card, you can always restore it using a few simple methods.
Instructions
Step 1
If you own a phone, contact the manufacturer for factory reset codes. These codes depend on your phone model. After you receive them, enter them using your phone. Depending on which code you used, your firmware will either be reset to zero, which will reset the settings, or the settings will be reset.
Step 2
If the phone does not belong to you, it was bought or found, or there is no way to contact the manufacturer, reflash the phone. To do this, you will need a usb wire, a flashing program and a new firmware. All this can be found on the Internet. Do not forget to save the phone's current firmware in order to restore data in case of an unsuccessful flashing.
Step 3
In case the password for the SIM card was lost on your phone, use the PUK code, with which you can recover the password. If you do not know it, contact your mobile operator, providing proof of ownership of the SIM card. To do this, you will need to contact the operator's office, taking your passport with you to identify you as the owner of the SIM card.
