摘要： A method for informing a telecommunications subscriber in a foreign country of at least one item of information. The telecommunications subscriber is assigned to a telecommunications provider in a home country via a customer relationship. The home country has a first time zone. The foreign country has a second time zone. The at least one item of information comprises the first time zone and the second time zone and is transmitted to the telecommunications subscriber when a mailbox provided by the telecommunications provider is used. The method includes transmitting the at least one item of information to the telecommunications subscriber via a voice message, announcing the voice message via an automatic voice message, and then playing back a call stored in the mailbox.
