            Abstract : 
Wireless coverage is often problematic. This is especially true for mobile radio networks, e.g., cellular networks. It is a very frustrating experience for a mobile user finding out that he is out of the coverage of his wireless service provider when he needs to send an emergency message. This paper proposes a method and system for delivering electronic messages over a wireless cellular communications network when the sender of a message is out of the coverage area. With this method the message is broadcasted repeatedly until a mobile wireless courier receives the message and stores the message. When the courier is within range of a base station of the cellular communication network, it then transmits the stored message to the base station for delivery
