Quick guide on how to get a duplicate sim card

Let’s face it: A mobile phone is futile without a SIM card. A phone will not allow you to perform the standard calling and texting functions. Therefore, a SIM card is crucial for the smooth functioning of a cellular device. In this article, we will walk you through the basics of a SIM card, how it works, and how it can get replicated with a clone SIM in detail below:

Basics of SIM Cards:


SIM or Subscriber Identity Module is specifically designed to store your mobile number.


How do they work?


SIM cards are usually connected to International Mobile Subscriber Identity (IMSI), which acts as a hub for all the global cellular networks. These include the popular Global System for Mobile Communication (GSM) and Long-Term Evolution (LTE) networks. To say the least, a SIM card is generally a gateway to global cell communication.


Every SIM card is then identified by a unique 64-bit SIM ID. This number is usually created separately for you. It is then shared with the International Mobile Subscriber Identity (IMSI) network as soon as the card is activated. After this, the phone automatically transmits your SIM card’s identifying information to the IMSI network.


Now that you know the basics of a SIM card, let’s proceed further to understand if it can be duplicated or not below:


Is it possible to duplicate a SIM card?


Yes, it is possible to duplicate a SIM card. However, it is not recommended as there is no guarantee whether two mobile phones will work properly with a cloned SIM card or not. There are chances that it may not be able to register both on the networks.


Despite these challenges, many people still go ahead with the duplication process by using SIM cloning tools, programmable cards, IMSI and KI numbers, etc.


Let us discuss the different methods of getting a clone SIM card in detail below:


Cloning SIM card using SIM cloning tool:

Here’s a secret. There are several sim cloning tools available in the market. However, choosing the best tool to clone your sim can be a tricky task.


One of the best SIM cloning tools is the MOBILedit Forensic, which allows you to extract the data, such as deleted data, call history, contacts, text messages, multimedia messages, photos, videos, recordings, calendar items, reminders, notes, data files, passwords, and data from apps such as Skype, Dropbox, Evernote, Facebook, WhatsApp, Viber, Signal, WeChat and so forth in a few clicks.


Listed below are some of the important steps that will help you with this process:


  • Install the software on your desktop
  • Remove the SIM card from your cellular device
  • Insert the card into the SIM card clone device and connect it to your desktop
  • Operate the SIM card cloning tool from the main toolbar. When the window appears on your screen, be ready to duplicate the SIM card
  • Select the ‘Read SIM button’ to read the content of your original SIM card. Once the data is read, choose the data which needs to be copied
  • Insert the writable SIM card to enable the write SIM button
  • Wait until the entire process is complete


Cloning a SIM card with Programmable Cards:

To perform this task, keep the following components mentioned below handy:

  • Blank SIM programmable cards
  • SIM firmware writer
  • Download Woron Scan
  • Targeted SIM


Once you have the above things handy, follow the steps mentioned below to know how to clone a SIM card with a programmable card:


  • Download the Woron software and connect your SIM card
  • Get the targeted SIM card and configure the software to clone the SIM card
  • Run the IMSI search. Once the results appear, make a note of it
  • Proceed with ICC search and write the code down
  • Run the KI search and take off the SIM card from the device
  • Install the SIM EMU software to write settings on the Blank SIM programmable cards. Insert it and locate the configuration tab, add all the details, such as KI, IMSI, and ICC, which were obtained from the Woron Scan process
  • After adding the necessary data, select the ‘Write to disk’ button and name the file as SuperSIM.HEX
  • Name EEPROM file as SuperSIM_EP.HEX and click on the Save button
  • Install the card with a SIM card reader and add all the required files
  • Finally, run the writing task to complete the cloning process


Cloning a SIM card using IMSI and Ki Number:

The IMSI code and KI (authentication key) number is an important element for SIM card cloning.


Let’s find out how to clone a SIM card using IMSI and KI numbers below:

  • Turn off your phone, remove the battery, and SIM card
  • Copy the IMSI number that appears on your SIM card
  • Insert the card reader in the SIM card slot and connect it to your SIM and desktop.


Once the entire process is complete, your new SIM card will be cloned.


While it is pretty easy to copy your SIM card for personal reasons with the above methods, you must also remember that it is also easy for someone else to make a copy of your card. So, to avoid this, make sure to always keep your phone with you at all times.


If an unauthorized individual gets hold of it, he will most definitely clone your SIM card. So, you should consider obtaining a replacement new SIM card whenever you are not in control of your device for an extended period of time.


In a nutshell, there are also other methods contrary to the above, where you can add the same mobile number in several SIMs and benefit from having the same phone number on different devices. For instance, if you have a hands-free device with your SIM card in the car, all you have to do is clone the same number in both terminals with different SIMs and follow the steps mentioned above to clone the SIM card easily!
