Will my promotional and transactional SMS from Exotel be delivered immediately or will there be a time lag?

Transactional SMSes are sent from Exotel immediately without any delay. They are mostly delivered within a couple of seconds after it is sent from your end. However, the same does not apply for promotional SMSes as there are time restrictions set by TRAI which we need to comply with. As per the latest TRAI regulations, Promotional SMSes are allowed only between 10 AM - 9 PM. Let’s say if you would like to deliver a Promotional SMS to a customer at around 10 PM which is clearly out of the deadline, we shall be able to dispatch this SMS only after 10 AM the next day.
