After switching to prepaid from a postpaid plan and configuring my plan through the my vodefone application, I had trouble accessing the internet via cellular data.

After calling up, restarting phone several times and manually confirming apn settings, the my vodafone app started to work via cellular data.

Unfortunately normal web browsing doesn't work as visiting https websites dont work and visiting any http urls end up redirecting me to http://www.vodafone.co.nz/myvodafone/ng/registration/, shown in the attached image.

The link to the play store to download the my vodafone application which i already have installed doesn't work as it is https.

Is there anything that can be done on my end to fix it as Ive already talked to several customer service reps in this process and they seemed to have no idea what could cause this, or whether the issue was on my end or vodafones.
