My wife has recently moved to an iPhone 3GS, and is on 2d prepay. Everything else is set up and working, but I have a question around the MMS settings.
Following the guide on www.2degreesmobile.co.nz/iphone, it mentions that mobile data must be enabled under the MMS section. She is on a casual prepay plan (may set her up with the 19data plan at a later date), so will this MMS setting 'unleash the hounds' in terms of mobile data usage?
With mobile data turned off, she is unable to send MMS messages.
