SIM Card

Subscriber Identity Module is the expansion of SIM card. It is a tiny memory chip which is used for all GSM mobile phones. Without SIM card the cell phone is considered to be dead. It is the life of mobile phones and even many youngsters too.

It contains the details of the subscriber, security data and memory space to store personal contact numbers and some text messages. It stores all the information which facilitates the network service provider to identify the caller. The data stored in the SIM card is used in selecting the network selection, based on the frequency of operation.
Since SIM contains all the information like phone number, text messages and other data, it can be called as a mini hard disk that can be inserted into any phone and the data can be retained. This helps the customer to change their handsets without losing important information.

SIM is a digital identification chip in mobile phones. It has the ability of validating and encoding which prevents others from tapping your call. SIM cards are usually region specific but they can work in all regions with the facility called Roaming which is facilitated by the network provider.

If ever the phone has been misplaced or stolen, it is possible to get another phone but it is a big task to get back all the contact numbers stored in the lost SIM. By using SIMKey Keyring Databank we can backup all the information. It’s a simple device in which the SIM need to be inserted and a simple procedure needs to be followed and the backup SIM will be ready.

As a development of technology, the SIM is used only in GSM phones. But in today’s world, GSM looks outdated and CDMA is coming into picture, There they don’t use SIM cards but instead they use a card called R-UIM (Re-Usable Identification Module) which is inbuilt in the phone and cannot be removed or changed to other handsets as in SIM cards.
