Finally, I got successfully installed by copying SSL certificate file to the phone and install it from there. Here are the steps. Check more details.
Usually we install Charles SSL certificate on the phone by browse the Charles SSL certificate link "http://www.charlesproxy.com/getssl" in a any browser, then it will install SSL certificate automatically without any worries as long as you phone connects to Charles IP that you can found in Charles "Help" menu.
