In other words, what is the maximum number of messages that can be sent out in a limit before they get rejected by RingCentral?

RingCentral high volume SMS throughput is up to 3 msg per second. That makes about 250K messages per day.

There is no max number of messages for high volume SMS API. However, there is a max size of the /batches API payload to post a batch and that is 50MB. So the numbers of messages per API call will depend on the message length and the way you send the message (broadcast or personalized campaign)
