RConnection + GPRS connectivity Issue

[gpalvia]

I am having a very strange issue

I am using N85

When i connect to GPRS ...5 out of 10 times i get an error. The error no is -4159.

void CSocketsEngine::ConstructL()
{
User::LeaveIfError( iSocketServ.Connect() );
}


TBool CSocketsEngine::ConnectL()
{
iConnection.Open(iSocketServ, KConnectionTypeDefault);
TCommDbConnPref prefs;
prefs.SetIapId(pAppUi->iConfig->AccessPoint()); // id of my Access Point
prefs.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
prefs.SetDirection(ECommDbConnectionDirectionOutgoing);
prefs.SetBearerSet(ECommDbBearerGPRS | ECommDbBearerCdma2000| ECommDbBearerCSD );
iConnection.Start(prefs,iStatus);
iState = EGPRSConnecting;
SetActive();
}
void CSocketsEngine::RunL()
{
switch(iState)
{
case EGPRSConnecting:
if(iStatus != KErrNone)
{
// iStatus.Int() retunrs -4159 WHAT CAN BE THE REASON?

}
break;

}

CSocketsEngine::~CSocketsEngine()
{
Cancel();
iConnection.Close();
iSocketServ.Close();
}


For connecting everytime...i create a new object of CSocketsEngine and delete any existing object.

I think this may also help u:
Try to find the reason by adding,
CEikonEnv::GetErrorText(TDes &aDes, TInt aError) const;
in your code..

// iStatus.Int() retunrs -4159 WHAT CAN BE THE REASON?

-4159

Can't connect to the Internet (not enough credit available on SIM).
