I'm not entirely sure how that's relevant at this point.
The user should be checking the Data Plan provisioning on their line (suggested above and is likely the cause of the trouble) and also checking to see if the etp.dat activation email is reaching the user's mailbox.
The activation email sometimes gets intercepted by spam/antivirus filters and fails to reach the mailbox.
