Dear Moderator,
My vodafone sim is not working with Xperia X10 mini pro and it is worked with another Phone.
same problem facing my friend with Xperia X10 mini/pro.
the SIM card it's probably too old. are the other phones that it does work Smartphones?
you shoud check with a new vodafone sim card 
Agreed, I suggest going down to the local Vodafone store an testing a new SIM card as this should determine where the issue lays.
