According to TRAI guidelines, promotional messages can only be sent to non-DND numbers between 9 am and 9 pm. However, transactional routes allow businesses to send non-promotional messages to DND numbers as well. This route is commonly used by banks and financial institutions to send important updates, such as payment notifications, to their customers.
