A roaming communication method in the field of communication technologies includes: obtaining a location update reject message sent by a Home Location Register (HLR) of a subscriber to a Visitor Location Register (VLR) of the subscriber; obtaining subscriber data from account information of the subscriber, where the subscriber data includes a local number and subscription information of the subscriber; and simulating the HLR to send the subscriber data to the VLR of the subscriber so that the subscriber can communicate in the visited network. The embodiments of the present invention also provide a roaming communication apparatus and system. The present invention enables a roaming subscriber to enjoy the communication service in a roaming network where no roaming agreement is signed without changing a Subscriber Identification Module (SIM). The solution is easy and convenient and saves expenses of the subscriber. At the same time, this attracts subscribers without roaming authority to use the network of an operator, thereby increasing the revenue of the operator.
