I'm on Vodafone NZ.  My girlfriend in Australia is on Vodafone Australia. 

All day yesterday, and so far today, my txts have not been reaching her.  Her txts have been reaching me though. 

I even tried txting her using a different vodafone mobile and phone number, but that didn't get through either.  I can call her mobile, and it works fine, but just isn't receiving my txts.  It can't be my phone, as I tried using another one too. 

We have both tried restarting phones etc.  No luck.

Do you have any suggestions?  Last time I experienced this was the New Years debacle nearly a year ago, when nothing worked.  This is just very frustrating.
