With Advanced Ads, you can define whether an ad can be displayed on all devices, mobile-only or desktop-only.

You don’t have to make any changes in order to display an ad on mobile AND desktop devices.

To display an ad on mobile OR desktop devices only, search for the Visitor conditions meta box and add the device condition.

Display by browser width

You can set specific device widths for which to display an ad with the help of the Responsive add-on.

Tablets and Mobile

By default, tablets are included in the Mobile condition. In order to exclude or target them specifically, there is a Tablet visitor condition available in the Responsive add-on.

Troubleshooting

This setting does not work properly on cached websites if you don’t use the cache-busting feature in Advanced Ads Pro.

What else you need to know

Tablet devices will normally be identified as mobile devices.

This option uses the wp_is_mobile() function included in WordPress (Codex). If you are unsatisfied with its functionality, have a look at the function in the WordPress core.
