Phoned up Vodafone earlier to complain about not able to get any data on my phone. After usual fannying about trying to get through automated systems and actually speak to a real person they checked and confirmed that there is not a problem with my phone, just terrible data coverage in my area.
Their solution? Well they don't have one. But they did send me a text to say that they have turned off my internet restrictions so I can now access 'adult content' sites (via my non existent data connection.)
Yeah, great. Thanks for that.
