enables a client to know whether ICC access is available and how to be notified

when this access is possible. The <codeph>RMobilePhone</codeph> also enables

ICC contains a number of applications one of which is known as the Universal

Subscriber Identity Module (USIM) application. </p> </li>

</ul> <p>The ICC stores the services available in the SIM Service Table (SST)

on a SIM, or the CDMA Service Table on a R-UIM. For DCS1800 systems, there

is also the Customer Service Profile (CSP). The services available reflects

the ICC applications static capabilities combined with the subscription details

of the user. </p> </context>
