I see now for $49.00, using Telecom's mobile broadband you get 3GB (http://www.telecom.co.nz/internet/mobilebroadband/plansandpricing/), whereas with Vodafone paying $50 only gives you 2GB.
Is there any intention to increase the amount of data one gets in current Vodafone Pre-paid mobile broadband plans, in the near future?
