The card holds a microchipthat stores information and encrypts voice and data transmissions, making it extremelydifficult to listen in on calls. The USIM Card also stores data that identifies the caller to theService Provider.Virtual Private Network: A Virtual Private Network (VPN) enables remote offices or users to gainsecure access to their organization's network over the public telecommunications network.This provides the benefits of remote access without the expense of dedicated leased orowned lines. VPNs work by using tunneling protocols, such as L2TP, to encrypt data at thesending end, and decrypt the data at the receiving end.
