Some phone manufacturers conclude a contract with telecom operators, in which the use of the device is stipulated only with the SIM-card of this operator. The phone has a special code that prohibits switching on the device with other SIM-cards. To untie the device from the operator, you will need to unlock it, or the so-called "unlock".
Instructions
Step 1
Jailbreak your phone. A jailbreak is a software operation for mobile devices on which the operating system iOS is installed. After the performed operation, access to the file system will be opened in the phone.
Step 2
To jailbreak, connect your phone to your computer and activate it. You need to activate the phone using the SIM card of the operator on which it is registered, or using the Gevey turbo SIM card (worth from 15 to 35 dollars). Make a backup copy of the data, to do this, hover the mouse cursor over the name of the phone, press the right key and in the tab that opens, select "Create a copy".
Step 3
Access the JailbreakMe website from your phone's built-in Safari app. The slider will appear on the display, slide it, then the jailbreak procedure will begin.
Step 4
Launch the Cydia application, which will appear immediately after jailbreak. Select the Search option. Type in the search line the word "ultrasn0w" (it is written through the number zero).
Step 5
Install the found application. The usual set of programs can be loaded at the same time. Restart your phone, after that you can use the communication services of any operator.
Step 6
If the mobile phone is not a complex device with an operating shell, unlock it by entering a special unlock code. It can be calculated for some series of phones using a special calculator. Service centers have code bases, specialists will also make an entry in the EEPROM of the mobile phone of "clean" blocks with missing information about the blocking.
