SIM Card
: Your BGAN Service Provider supplies you with a
Universal Mobile Telecommunications System Subscriber SIM
(SIM) Card.
The SIM card is similar to the SIM Card that is commonly used
in a GSM phone. The card holds a microchip that stores
information and encrypts voice and data transmissions, making it
extremely difficult to listen in on calls. The SIM Card also stores
data that identifies the caller to the BGAN Service Provider.
Virtual Private Network
: A Virtual Private Network (VPN)
enables remote offices or users to gain secure access to their
organization's network over the public telecommunications
network. This provides the benefits of remote access without the
expense of dedicated leased or owned lines. VPNs work by using
tunneling protocols, to encrypt data at the sending end, and
decrypt the data at the receiving end. This "tunnel" cannot be
accessed by data that is not properly encrypted.
