I'm not entirely sure how you would recognize traffic from a specific mobile phone, as individual device identification can be complex and often requires app-level permissions or device-specific identifiers, which may not be accessible via standard web tracking. However, we can serve ads through IP targeting. This means that if a particular mobile phone is connected to a specific IP address, such as a home or office Wi-Fi network, ads can be delivered to all devices using that same network. It's important to note that this method does not isolate the ad to just one mobile phone, but rather targets the entire network. I hope this clarifies the process and helps with your campaign planning or targeting strategy.
