Not for nothing but I just found a load of charges on my mobile bill from Group texts I've sent that my carrier has identified as Picture messages and thus charged me. This is due to the "Send group as MMS" setting in the phone. So your network thinks that you are sending data as opposed to text. Disable this setting in the phone to avoid extra charges and recover the ones you've had, my carrier (3) refunded me over ?30.
I have unlimited data and texts but picture messages are not covered, I don't think they are in any tariff on UK networks.
