Part 5: How to Copy SIM Card with IMSI and KI Number

The SIM card contains the International Mobile Subscriber Identity (IMSI), which serves as an ID number to identify it with the operator. The IMSI is essential for the cloned SIM to work properly. Another important data is the Authentication Key (KI), which authenticates the subscriber with the operator and allows for SIM card cloning. Know how to clone SIM cards using IMSI and KI numbers:

• Power off the device, remove the battery, and take out the SIM card.
• Note down the IMSI number displayed on the SIM card.



• Get a SIM card reader online and insert it into the SIM card slot.

• This will allow the KI number to duplicate the content.
• Once the process completes, the new SIM card will become an identical twin.
• Insert it into your device and power it on to start using it.

Part 6: How to Clone a SIM Card via Programmable Cards

To back up data in case of a lost or stolen device, you can use a SIM card copier. (What if your phone is lost or stolen?) With programmable cards, cloning your SIM isn't that tough. You'll need a blank SIM programmable card, a SIM firmware writer, the target SIM, and a software tool for reading. See how to clone SIM cards using programmable cards:

• Connect the SIM Reader and install Reader software, such as Woron. Proceed to configure the software.
• Next, initiate the IMSI search and note the results as they appear.
• Then, proceed to launch the ICC search.

• Download the SIM-EMU software to write settings on the Blank SIM Card.
• Insert the SIM card and run SIM-EMU. Go to the configuration tab and input all the data obtained from the scanning process, including ICC, KI, and IMSI. You can include the following information: Abbreviated Dialing No. (AND), No. of SMSes stored on the SIM (SMS), and Fixed Dialing No. (FDN).
• Enter the values as AND/SMS/FDN# - for example, 140/10/4. Make sure to write the number in an International Format, such as +44 (UK) 7777777777.
• Select the "Write to Disk" button and name the file SuperSIM.HEX. An EEPROM file window will appear.
• Set the EEPROM name as SuperSIM_EP.HEX, then click the "Save" button.
• Flash the file onto the Blank SIM Card and install the card using the card writer.
