Abstract
Mobile communication plays a vital role in every human's life. The basic requirement to initiate this communication is a mobile signal. A mobile signal, which is also known as reception, is the signal strength received by a mobile phone from a cellular network. This signal is detected by the SIM (Subscriber Identity Module) card that is inserted into the phone and helps to send and receive calls/text messages. Various network (signal) providers include Airtel, Vodafone and BSNL etc, whose primary goal is to facilitate their customers with their best reception. But, at the situations where the signal vanishes, the network subscribers (users) become helpless.
In this paper, we suggest a method which helps the subscribers to gain signal from other network providers, in case of emergency situations, when their own network provider has failed. This is implemented by making changes in the ICCID (Integrated Circuit Card ID) of the SIM. By implementing this concept, we can also provide signal to those subscribers in the dead zones of a particular network, where a dead zone is defined as an area in which mobile phones cannot transmit to a nearby tower or a base station.
