keewee01: I knew this was going to be an issue before I ported - I didn't make the move to 2degrees lightly or blindly/
Always do your research first.
That's the thing - I did research, and even asked 2Degrees. Obviously I missed seeing a thread here but 2Degrees only referred me to http://www.2degreesmobile.co.nz/help and said that I should contact them if I have any issues sending or receiving txt messages from Twitter or Google. Even at the store on Sunday the staff said there shouldn't be any problems. Nobody said the service doesn't work at all and is not even set up.
Perhaps this should be added to the 2Degrees FAQ's so people are aware of it.
