How to Install a Digital Certificate on Your Apple iPhone

After you download your Certificate from your PC, you may export it and send it to your email along with the Intermediate and Root Certificate.

1. Once you've received it on your phone, start installing the Root Certificate.
   Hit install, and you will receive a message to continue to install.
   It will change to "Verified" if you install it properly.
   
   
2. Now install the Intermediate Certificate using the same process. 
    

   

    

3. Now, install your PersonalSign Certificate. It will ask for your private key password (this is the password that was auto-generated when you downloaded the Certificate.)

   

    

4. Now go to Settings > Profiles.
   Under Profiles, you will find three profiles.
    

   

    

5. Now go to your account and passwords.
   
   
6. Select the email account for which you are installing the Certificate.

   Make sure "Sign" is turned on and the certificate selected.
   After that, make sure you close all.
