For some reason the mmsgallery.telecom.co.nz site is no longer working when I browse to this on my mobile (running Android 4.0.4). When I enter the mobile number and password it logs me in and just returns a page saying Error - Sorry, this feature is not enabled. I have tried using both Chrome and standard Android browser and get the same result.
If I browse to the same site using a PC browser, and login with the same account I am able to browse MMS messages ok
This site used to work just fine on my mobile browser. I am not sure what has stopped this working.
