Today I've changed my account from one plan to a Smartphone 60 plan. After that the Telecom Portal spphone.telecom.co.nz would say "your account information is not available".
I thought it was related to my plan change.
After the Windows Phone Mango update the page now redirects to login.telecom.co.nz instead of going directly to the account status.
So what's going on? Account information not updated yet, or handset not authenticating to the network correctly?
