o2 pay as you go sim

[MysticMeg]

I've noticed for quite some time that my pay as you go sim still allows me to send bbms check email on internet when put into a blackberry. It works instantly. I haven't even topped the sim up for use on BIS. Anyone else had this lucky thing happen to them also?

I've not topped up in 6 months and I've had BIS since, but I'm on Orange UK, kind of weird for them to be so careless with BIS, I know loads of others who have had the same luck.
