Method and device for performing communication by using virtual subscriber identity module

A server comprising:

• at least one processor;
• and
• a memory;
• wherein the memory comprises instructions that when executed by the at least one processor, cause the server to perform, at least, the following:
• receive a request for allocating a virtual subscriber identity for a first device sent by a second device;
• allocating the virtual subscriber identity for the first device, wherein the virtual subscriber identity is corresponding to a communication number of the second device;
• establishing a charge association between the virtual subscriber identity of the first device and the communication number of the second device;
• and
• add a first charge generated by the virtual subscriber identity to a second charge associated with the communication number of the second device according to the charge association when the first device accesses a network via the virtual subscriber identity.

A communication system comprising a first device and a second device, wherein the second device is communicatively coupled with the first device, and the second device having a communication number;

• and, wherein
• the second device is configured to:
• send a request for allocating a virtual subscriber identity for the first device to the server;
• and
• send a data package to the first device via a short range communications connection, wherein the data package comprises first information associated with the virtual subscriber identity corresponding to the communication number;
• and
• the first device is configured to:
• receive the data package from the second device via the short range communications connection;
• obtain the virtual subscriber identity according to the first information in the received data package;
• and
• access a network via the virtual subscriber identity, wherein a first charge generated by the virtual subscriber identity when the first device accesses the network via the virtual subscriber identity is added to a second charge associated with the communication number of the second device according to a charge association between the virtual subscriber identity of the first device and the communication number.
