At this moment I can't but I should have been clear that the callback was from CallbackWold (CBW), a now defunct callback service that was popular with the members of this forum. They had a callback trigger via web page. I realized that this page just created a URL and the URL actually triggered the callback. By saving the URLs of commonly called number combinations on my phone I could trigger callbacks with virtually no roaming data usage.
