Indian Prepaid cellular users are bombarded with class 0 messages (balance/last call charge message) when they either call/text/use data. Most of these messages are displayed as popup messages and these messages  require the user to save or dismissed. These messages are also used for promotional offers and are annoying in nature.

Eg. If a user is using SMS for conversation then after every outgoing message a class 0 message pops up stating the amount charged for last message.

Solution : Network providers should gice an option to it's users to enable/disable class 0 Popup messages.
