Hi briankaji,

Thank you for your post and welcome to the forums!

There are a couple of things you can do. 

Try to update your phone firmware using Firmware Over The Air, if your operator supports this.

Re-install the phone firmware using Nokia Suite / Nokia PC Suite. This should re-install the certificates as well. 

If the problem still persists, visit your nearest Nokia Care Point. 

Let us know if this helps,

Puigchild
