dear sir,is there is any procedure so that we can stop to activate the mobile valu based services electronically i.e. if we give application in written to service provider that none of your value based services should be activated electronically.for ex.by pressing * and 9 caller tune is activated.we do not want to activate this service if by mistake any of our child press this and we have given application for this not to activare our services without our written and confirm application on paper.reply immediately.
