Because no mobile company in NZ can seem to think for themselves Voda now have the same mobile bb plans as telecom at the same price point (without the loyalty discount required for telecom's deal).
The link below seems to suggest that I can migrate to the new plan (2gb for the same price) from my current 1gb plan with no transfer fee, anyone know if that's correct.
