For the security of the owner's data, several types of blocking are used, to remove each of which you must perform a certain sequence of actions.
Locking the phone for the operator is designed to protect the phone from using the phone on a network other than the original one. In this case, when you turn on the phone with a "foreign" SIM card, an unlock code is requested, otherwise the phone is locked and its use is impossible. Contact the operator's representative using the contacts located on its official website. You can find the site address on the package from the SIM card or using a search engine by entering its name. Provide your imei phone number and any additional information you may need. You may also encounter this type of protection, such as blocking the device. It is designed to keep your personal files stored on your phone safe in case your phone is stolen or lost. In this case, when you turn on the phone, you will be asked for a password that must be entered to unlock. To reset it, you can use the factory reset code or the firmware reset code. The first code will reset all settings to the original ones, while the second will lead to the loss of all your data stored in the phone memory. Contact the manufacturer of your phone, providing the imei code, as well as any additional data that may be required. To protect the SIM card, without which the use of a cell phone is impossible, a PIN code is used that blocks it. In case you have forgotten the pin code, use the pack code. You can find it on the plastic packaging of the SIM card. If you are unable to use this method, contact the operator's representative. Provide your passport details as well as additional details that will be requested. You will be given a new SIM card to replace the old one. Thus, you will save the cell number assigned to you, but all your data stored on the old SIM card will be lost.
