Retrieve Message Waiting Information Tutorial

This tutorial describes how to retrieve a message waiting information.

2. Retrieve the set of message waiting indicators from the current ICC using RMobilePhone::GetIccMessageWaitingIndicators(). Indicator values are described by RMobilePhone::TMobilePhoneMessageWaitingV1.
3. Set the message waiting indicators on the current ICC using RMobilePhone::SetIccMessageWaitingIndicators().
4. Use RMobilePhone::NotifyIccMessageWaitingIndicatorsChange() to get the notifications of any changes to the message waiting indicators on the current ICC.
