Interstitial ads show over wifi, but don't show over mobile data

[Pierre]

I started an Admob campaign a few days ago for a Unity project and noticed that ads only shows up in wifi.
With mobile data (4G), I wait 60 seconds to be sure but still no ads shown ...
My dev phone haven't any ads blocker in it.
Any clue ?

Hi Pierre,

There are a number of factors that could result to ads not showing. Could you test your Ad unit Id/s in question with our sample app under a mobile data (4G) connection and see if the issue is reproducible?

For us to check on our end, would you share with us privately the Ad Unit Id/s in question? I will send to you a private email where you can send your Ad Unit Id/s.

Hi Ivan,

With the sample app under mobile data (4G) connection, I confirm the issue is reproductible (no ads shown).
With wifi, it's working.
Ad Unit ID sent ;)

Pierre

Hi Pierre,

Thank you for confirming and for providing the Ad unit Id. Since the issue is only reproducible under a mobile data (4G) connection and ads are showing over Wifi, then it's safe to assume that there is nothing wrong with your implementation. This seems to be a Network specific issue.

Could you try testing the app under a different Mobile Data Network and see if the issue persists? 

For us to further investigate on our end, would you be able to capture the Charles session (with SSL Proxying enabled) while trying to display the ads under the mobile data (4G) connection? This will give us a clearer picture on the Ad Request details sent as well as the corresponding response returned on your end.

Hi Ivan,

It's the same on 3G mobile data network.

Best regards,
Pierre

Hello Pierre, 

Ivan is out of office, I will be assisting you on his behalf. Thank you for confirming this. As requested earlier, would you be able to provide us the Charles Logs with SSL Proxying enabled, while trying to display the ads under the mobile data (4G) connection, so we can take a look at the Ad requests being sent in this network.

Thanks,

I don't understand how Charles is working..

[Pierre]

So I installed another software (packet capture) on the Android Samsung Galaxy S4 to capture packet with SSL decryption and ... ads are now shown!
If I use SSL decryption, ads are shown, if I don't, they don't show..

Hello Pierre, 

Glad to know that you're able to load the ads. Feel free to write back to us if you have any further questions.

Thanks,

Hello Bharan,

No it's not working. To summarize, ads are only shown when I use a SSL decryption proxy like Charles Proxy ...
When I use normal mobile data, ads are not shown.
That's very strange, any clue why it appends?

Hi Pierre,

A private email was sent to you previously where you could respond with the Charles logs privately. Would you be able to try capturing the Charles session when issue was encountered? You may refer to this guide to help you with setting up Charles in your end.

I am having a similar issue where banner ads are being shown when the device is connected over wifi, but not showing when connected over 4g.  This is on an ios device with an Ionic app using the cordova-plugin-admob-free plugin (v0.12.1).

Hi guys, I am having the exact issue.

In WIFI ads are showing.

But using my 4G, 3G nothing is showing.

If for me that s doesn't work, that could mean that all my users couldn't see the ads.

I have this issue when I am using this code on lines:

        {
            if (Advertisement.IsReady())
            {
                Advertisement.Show();
                Debug.Log("ShowAds");
            }
            else
            {
                Debug.Log("NOAds");

instead of just:

Advertisement.Show();

Thanks guys for your hep :)

Hi everyone, 

If ads are showing on Wifi but not on 4G or 3G, then this seems to be more of a network specific issue.

However, as this forum can only cater to technical questions specific to the code implementation of the official Google Mobile Ads Unity plugin or the Google Mobile Ads SDK, it will be best that you contact directly the developer team of the corresponding frameworks or tools that you are using for development. We have no visibility over their inner workings so we can't guarantee that the features of AdMob and/or the Mobile Ads SDK will work as expected. 

On another note, you may want to use the official Google Mobile Ads Unity plugin to mediate with Unity Ads by following this guide. Feel free to create a new thread if you need further assistance with mediation.

Did you ever figure out or get an answer to why Ads only show when connected to wifi ?

I have a guess, it's because my network operator doesn't properly send the country information.

For example, with Youtube app on 4G or 3G, the main page doesn't shows up.

If I use Wifi, then my country info are sent and the main page shows up.

 

Currently no fix for that as it's Google related.

Hi Pierre,

Given that you were able to display ads on some network, we can confirm that the code implementation of the Mobile Ads SDK is working and that the issue is not specific to the SDK and more of a network-related issue.
