I am trying to register to the EE website as well as to the application for the first time, but it is not letting me in. I always get stuck in the 'link' section in the application registration. After Register and Verify, when I was asked to put a phone number, the next page comes with an error message which can be seen in the attached image (image 1). I cannot even top up and access my account for that issue.

Please suggest me a solution.
