SMS Rate Limiting
To prevent over-calling of SMS resources by specific users, Unimatrix supports limiting the frequency of sending SMS messages, thus blocking useless requests and effectively controlling SMS delivery costs. You can choose to enable and specify speed limit rules for the same phone number by minute, by hour, by day (natural day).
This feature is an extension service and is not enabled by default. Please go to Extensions - SMS Rate Limiting in the Console to configure according to your actual needs.
Phone Number Whitelist
If you have phone numbers that you expect to be sent infrequently, you can set them up using the number whitelist feature. Please fill in the numbers in
E.164 format, separating multiple numbers with commas, and add up to 50 records.
