I've been using the Free2Txt from Vodafone as I ran out of credit.  This is a great tool for people like me who run out and need to be paid to top up again.  So Bravo Vodafone!

Just confused, you get 20 free texts per day - but this morning, I sent a text and it said I have sent 8 texts already...when I've only sent two 0.o

I guess it is broken?
