Cell phone lock is used to protect the owner's personal data in case of theft or loss of the mobile. Also, you may encounter a phone lock for an operator, which will not allow you to use it on any network other than the original one. In each case, there is a specific sequence of actions that must be taken.
Instructions
Step 1
The SIM card is blocked due to the three times entering the wrong PIN code. There is a possibility of removing the pin code. To do this, you need to enter the pack code located on the package from the SIM card. After you enter it, you will be prompted to enter a new pin code. If this attempt fails, contact your mobile operator's office. Request a replacement SIM card. This will require passport details and the physical presence of the owner of the phone number.
Step 2
Phone operator lock is used to prevent the device from being used on a network other than the original one. In this case, when you turn on the phone with someone else's SIM card, a request for an unlock code appears. You can get this code by contacting the operator's representative. Justify your request by the fact that you want to use your phone while traveling, but do not want to overpay for roaming. Provide your phone serial number and owner details for verification. Use the received code to remove protection.
Step 3
If your phone is locked with security codes, and you do not remember it, contact the representative of the manufacturer of your device. You will need a firmware reset code or a factory reset code. Provide your phone serial number and enter codes. Keep in mind that using the firmware reset code will reset the phone to the factory state, i.e. will erase all existing personal files. Using the reset code will allow you to keep the personal information stored on your mobile, but will return all settings to factory defaults.
Step 4
In case the previous step failed, please re-flash your phone. Use sites such as allnokia.com or samsung-fun.ru to find programs and instructions for synchronizing, as well as further updating the cellular firmware.
