Have has some issues using data on my phone (HTC Wildfire) while outside the main centres (specifically outside Christchurch).

Before December last year I was on pre paid and the data packs worked fine outside Christchurch.  The next time I was outside Christchurch was in January when it no longer would work.  Between this time I had switched to pay monthly and had visited Australia using a Virgin Sim in the phone, though not sure if either of these would have affected it.  The data still works fine in Christchurch.

I did notice that I was using the APN: http://m.2degreesmobile.co.nz/ and have changed this now to the APN: internet and have data roaming turned on though am not sure if this will help.

Have not contacted 2 degrees yet as am sure I have done something wrong in the settings on the phone.

Any advice would be much appreciated.
