Abstract: The present disclosure encompasses a system and a method for availing a data service by a user equipment [110] in an international location. In an embodiment, the user equipment [110], in the international roaming, transmits an attach request to a second network, wherein the user equipment [110] configured with a SIM [120]. The user equipment [110] then receives a rejection message or an acceptance message from the second network based on the attach request. On receiving the acceptance message, the user equipment [110] establishes a connection with the second network to extract an IMPI from the SIM, an IMSI from the IMPI; and a network parameter from the IMSI. The user equipment [110] then identifies a configuration parameter of the home network, corresponding to the network parameter. Finally, the user equipment [110] avails the data service using the configuration parameter.

Abstract: Embodiments of the present disclosure relate to availing at least one service by a user equipment while one of in an international roaming and leaving the international roaming. In a preferred embodiment, a method for automatic IMSI switching by using the proactive commands such as PLI commands, while entering and leaving the international roaming, independent of the cause code sent by any operator and can work regardless of the cause code received is disclosed. The method includes replacing of the home IMSI of the user equipment with the global IMSI in an event the at least one network parameter corresponds to the second location and replacing of the global IMSI of the user equipment with the home IMSI in an event the at least one network parameter corresponds to the first location.
