Do you know what a SIM card is? It is a Subscriber Identity Card usually known as SIM which we insert in our mobile phones for the purpose of communication. It is also defined as integrated circuit card as it is embedded with one. SIM is a microprocessor used for other purposes too for the storage of personal data in your Bank credit cards and employment cards.

Generally we think that a single SIM card can support a single network connection only and if we want to use two network connections in one phone we buy dual SIM support mobile phones. But there exists a technology with which we can use a single SIM to support multiple network connection. This is possible with the help of magic SIM gadget, which is easily available in the market now. All you have to do is to buy a blank SIM and a SIM card reader from the market. The blank SIM and the SIM card reader come along the instruction manual which tells you how to copy the SIM card information. You just then copy the details of your SIM card into the blank SIM card. You can copy multiple (maximum six) SIM’s data on a single blank SIM card and use it. This helps you to avoid opening the cell phone again and again and changing the SIM cards. All you have to do is to switch off the cell phone and then turn it on again and select the network which you want to use. There are some limitations to this technology that only one network could be turned on at a time. Like dual SIM supporting mobile phones it does not allow you to keep all the connections turned on at a time.

Although, this magic gadget SIM has some limitations but it is a very useful device. People who travel a lot to different countries can take benefit of this device as they do not have to change SIM’s again and again. They can just load the data of their different SIM’s of different countries and enjoy the ease. They can also keep the entire contact list in one SIM card. There is a possibility that the shopkeeper or the person doing this job for you keeps the copy of your SIM data in his system and load that information on another blank SIM card and use your SIM simultaneously. Therefore, it is advised to carry out the whole process your self without the help of any other person or shopkeeper.
