Abstract
A removable card for use with a mobile wireless communication device has a processor and a non-volatile memory, connected to the processor. The removable card has electrical connections for connecting to a mobile wireless communicating device for use by a user to access a common carrier network to access a network of interconnected computer networks (“Internet”). The card comprises a processor and a non-volatile memory connected to the processor. The non-volatile memory has two portions: a first portion and a second portion. The first portion is accessible by the provider of the common carrier network with the processor restricting access thereto by the user. The second portion is accessible by the provider of the common carrier network and with the processor granting access thereto to the user for storing user data therein. Finally, the removable card has logic circuit for encoding the user data to produce encrypted user data, for storing in the second portion.
