Restrictions on SMS Messaging

Messaging time requirements are as follows:
- Except for user-triggered messaging, your enterprise should not send SMS messages beyond 07:00 to 21:00.
- If you do need to send urgent events from 21:00 to 07:00, SMN allows you to send 100 messages containing the same content at most.

Maximum number of messages sent to each phone number
You can send a maximum of 10 messages to each phone number within a day. If you need to send more, provide a phone number whitelist.
