Abstract: A processor (103) in a wireless terminal (10) executes a communication service application to thereby perform an operation as a client for using a communication service. Further, in an abnormal situation where the wireless terminal (10) cannot access a server system (50) of an operator of the communication service, the processor (103) executes a predetermined activation procedure in the wireless terminal (10) without passing through the server system (50) to thereby activate a special account in the wireless terminal (10). This makes it possible, for example, to perform communication by the special account using an online service application installed in the wireless terminal during an abnormal situation where the wireless terminal cannot access the online service server.
