All sender IDs will be overwritten with a shortcode to ensure delivery.
Dedicated longcodes can only support inbound SMS.
We can not guarantee delivery between 9pm to 9am Indian local time. We will still attempt to send the messages, but due to local regulations, they may be filtered.
We can set up 2-way messaging on our Indian shortcode. A higher rate per message will apply, contact our 24/7 support team to have this set up on your account.
