Phone Identification Tutorial

This tutorial describes how to retrieve the phone identification parameters from the device.

The phone idenitifcation is returned in a packaged CTelephony::TPhoneIdV1. It contains the following member variables, each a TBuf descriptor of up to 50 characters:

Manufacturer
Model
Serial Number, the IMEI or ESN serial number. It identifies the phone, not the subscriber using the phone.

create an instance of CTelephony with an active object
set the active object with SetActive() function
use CTelephony::GetPhoneId() to get the phone identification parameters use CTelephony::EGetPhoneIdCancel to cancel the asynchronous call.

Phone Identification example

#include <e32base.h>
#include <Etel3rdParty.h>

class CClientApp : public CActive
   { 

private:
   CTelephony* iTelephony;
   CTelephony::TPhoneIdV1 iPhoneIdV1;
   CTelephony::TPhoneIdV1Pckg iPhoneIdV1Pckg;

public:
    CClientApp(CTelephony* aTelephony);
    void SomeFunction();

private:
    /*
       These are the pure virtual methods from CActive that  
       MUST be implemented by all active objects
       */
    void RunL();
    void DoCancel();
   };

CClientApp::CClientApp(CTelephony* aTelephony)
    : CActive(EPriorityStandard),
      iTelephony(aTelephony),
      iPhoneIdV1Pckg(iPhoneIdV1)
    {
    //default constructor
    }

void CClientApp::SomeFunction()
    {
    iTelephony->GetPhoneId(iStatus, iPhoneIdV1Pckg);
    SetActive();
    }

void CClientApp::RunL()
    {
    if(iStatus==KErrNone)
       {
       TBuf<CTelephony::KPhoneManufacturerIdSize> manufacturer = iPhoneIdV1.iManufacturer;
       TBuf<CTelephony::KPhoneModelIdSize> model = iPhoneIdV1.iModel;
       TBuf<CTelephony::KPhoneSerialNumberSize> serialNumber = iPhoneIdV1.iSerialNumber;
       }
    }

void CClientApp::DoCancel()
    {
    iTelephony->CancelAsync(CTelephony::EGetPhoneIdCancel);
    }
