In traditional phone cloning, fraudsters used to clone devices via monitoring signals between phones and cell towers. In this way, these people used to make expensive calls like international calls on the phone bill of others. Nowadays, phone cloning is not that common. All thanks to the digital network system. However, it can happen when calls fall back on the analog system in some specific areas.

Digital networks signify that multiple signals can use the similar channel that a single analog call once used. As a matter of fact, signals are binary now, that makes the scanning of cell signal really difficult. However, there is a drawback of this digital network system, which is analog backups.

In areas with high traffics, several carriers maintain analog cell stations to handle the overflow. If a single station becomes a kind of busy, it diverts calls on the analog network. People who own a scanner within that network range can yield the IMEI of your mobile device. This is what they require to clone your phone.

Now, digital systems make use of the GSM technology that uses the IMEI number of the phone. It is not really easy to get hands-on the IMEI number. In the first place, you need to capture the IMEI number and then, employ a SIM reader and writer to replica the SIM.

With the help of an empty SIM and SIM cloning tool, one can write the IMEI number on the empty SIM within a few seconds. SIM readers and writers are easily accessible in many online stores.

Fix Cell Phone Cloning

The first action you should take if you feel that your phone has been cloned is to get a new SIM card. Whether your carrier is on the CDMA network (Sprint and Verizon) or the GSM (AT&T and T-Mobile) network, updating the SIM card number within the carriers system means the hacker can no longer use your phone number.

It is not likely that someone can clone a cell phone that is attached to an eSIM. This type of SIM card is hardwire into newer smartphone models. Such as the Google Pixel models and the newest iPhones.

You can always buy a new cellphone, but changing the SIM card should suffice. It is important that you shred or dispose of your old SIM cards properly. The CDMA network SIM cards are reusable but only compatible with your phone’s IMEI number once activated.

GSM carriers allow you to swap your SIM card between any model of the phone. But once a new SIM is activated on your phone number, the previous one is disabled. This means that if you activate a new sim card, the old one will no longer work. that is the best option I guess.
