The present invention relates to a method for providing a roaming service of an international call, as a roaming method of a mobile terminal, comprises, in an international roaming mode, checking TON (Type Of Number) of an incoming number attempted to originate a call; in the case that the TON of the incoming number is not an international call, checking whether the incoming number is a telephone number of a home network or a telephone number of a visited network; and in the case that the incoming number is checked as a telephone number of a home network, changing the incoming number into an international call number using a home country code (CC) stored in a storing unit, changing the TON of the incoming number into an international call, and requesting call origination to the incoming number, and in the case that the incoming number is checked as a telephone number of a visited network, requesting local call origination without number change.
