Subscription
is the contract that you have with the service/network provider. To use your
phone, you need to have a subscription to a network. You get a SIM
(Subscriber Identity Module) card with your subscription. The services
included in your subscription depend on your choice of operator and/or
subscription. So some of the services and functions described in this manual
may not be accessible to you. If you want a complete list of the services
included in your subscription, please contact your network operator.
Two Line Service
enables you to have two lines and two different phone numbers on one
subscription for your mobile phone. This makes it possible to have separate
numbers for business and personal calls. To use this service, it must be
supported by your network.
WAP™
The Wireless Application Protocol (WAP) is an open, global specification that
makes it possible for mobile users with wireless devices to access and interact
with information and services easily.
