SIM card
Subscriber Identity Module card – a card that must
be inserted in any GSM-based mobile phone. It
contains subscriber details, security information
and memory for a personal directory of numbers.
The card can be a small plug-in type or credit card-
sized but both types have the same functions. Your
phone uses the small plug-in card.
SMS
Short Message Service. Allows messages of up to
160 characters to be sent and received via the net-
work operator's message centre to your mobile
phone. Messages are stored if the phone is off or
out of reach ensuring that they reach you. To use
this service, it must be supported by your network.

HTML, WML is designed to fit small handheld
devices.
WMLScript
WMLScript can be used to enhance the functional-
ity of a service, just as, for example, JavaScript
may be utilized in HTML. It makes it possible to
add procedural logic and computational functions
to WAP-based services.
