Abstract

The invention can allow data to be transferred from/to an electronic device when a removable Subscriber Identity Module (SIM) card that stores information used to register the electronic device with a communications network is absent from the electronic device. A subscriber may, therefore, upgrade from an existing radiotelephone to a new radiotelephone without the need for two SIM cards so that both radiotelephones operate to transfer the data. For example, according to embodiments of the invention, a subscriber can transfer data from the existing radiotelephone to the new radiotelephone even though one of the radiotelephones does not have a SIM card.
