How do I stop the credit notification on my Nokia?

[buzzybee]

I have a Nokia 6101 and whenever I send a message or make a call I recieve a notification informing me of my remaining credit - which causes the message alert tone to go off. Does anyone know how I can stop getting this notification, or at least stop my message tone from sounding at this time? (I do not want my message tone to stop going off when I receive an actual message) Thanks!

this usually just happens when you are on O2, if you are then you'll have to ring O2 up n see if you can stop this. if not then i dunno! :o)
