Abstract: What happens, if we mistakenly send an SMS [Short Message Service] to a person to whom it was not meant to be? Can we Recall/Delete message before it is read by the receiver? Currently, we do not have a provision in SIM [Subscriber Identity Module] by which we can Recall/Delete the sent message before it is read by the receiver. This Paper talks about a facility to be provided in SIM in the form of an Application where a Recall/Delete Message facility can be provided to the end user. Through this facility, one can Recall/Delete the message sent to a particular recipient, if he/she has not read the message.
