How to Clone a Cell Phone Without a SIM Card

1. Find the security menu on your cell phone. Every brand of cell phone has a different method for accessing the security menu, and it can be hard to find. This information is unlikely to be in your user manual, so you will most likely need to look up the directions for locating your phone's security menu online. Websites that offer free information for cellphone hacks are a good place to start the search for the method to access your security menu.
2. Find your phone's electronic serial number (ESN). Every phone has this number, and it is usually the same number as its standard serial number. You can find the serial number by removing the back of your phone, taking out your battery, and finding where it's printed behind the battery.
3. Get the phone you'd like to clone the information to and access its security menu.
4. Change the cloned phone's ESN to match the original phone's ESN using the cloned phone's security menu.
5. Find the code that allows you to change your phone number. All brands of cell phone have a specific code for use in the security menu that allows you to change your cell's phone number. As this code will definitely not be available with any of your phone's documentation, you will need to find your phone's specific code online, which you can probably do at one of the sites mentioned earlier.
6. Change the phone number of your cloned phone to match the number of the original using the security menu and the code referenced in the last step.
7. Make a test call to ensure the cloned phone functions.
