Method for updating a file in a data processing system that includes a first file (efprl) that stores information data can be updated through a network of tranSmissu00e3o data, the data processing system that includes a first file (efprl) that stores data information can be updated through a data transmission network.The smart card (card) that incli a first file (efprl) that stores data information can be updated through a data transmission network.And computer program to a data processing system that includes a first file (efprl) armazamento information data can be updated through a network of tranSmissu00e3o data.Method for updating a file in a data processing system that includes a first file (efprl) storing information data can be updated through a network of tranSmissu00e3o data, characterized by the fact that this system comprises at least a second file (efmr) having the same structure as the first file (efprl)The second file (efmr) storing updates of information data received from the data transmission network.By the fact that when the first file (efprl) needs to be updated, this method comprises the step of renaming the second file (efmr) by the name of the first file (efprl).In particular, the data processing system is a SIM card of a mobile phone and these files include preferred roaming list (PRL).
