title: AdMob test banner loads on simulator, Only real banner loads on device?
body: <p>I can't get a test banner to load on a device. However, test banner loads on simulator no problem. I'm trying to test my AdMob/iAd singleton mediation. It works fine with test ads on simulator but AdMob never loads the test banner on actual device.</p>
  
  <p>The following is the code to present AdMob banner: </p>
  
  <pre><code>    self.adBanner_=[[GADBannerView alloc]initWithFrame:CGRectMake(0, 0, 320, 50)]; 
  
      adBanner_.hidden=NO;
  
      adBanner_.delegate = self;   
  
      adBanner_.adUnitID = @"Unit-ID";
  
      GADRequest *request = [GADRequest request];
  
      [self.adBanner_ loadRequest:request];
  
      self.adBanner_.rootViewController = self;
  
      [self.view addSubview:self.adBanner_];   
  
      isLoaded_ = YES;   
  
      //  request.testDevices = @[ GAD_SIMULATOR_ID ]; &lt;--loads test ad on simulator
  
      request.testDevices = @[ @"number" ];  &lt;--supposed to load test ads on real device
  </code></pre>
  
  <p>Why aren't I receiving AdMob test ads on real device yet there's no problem with AdMob test ads on simulator? Is code wrong?</p>
