The default frequency limit for Tencent Cloud SMS is 50 messages per phone number per minute. This limit is designed to prevent abuse and ensure fair usage for all users.
For example, if you send 50 SMS messages to a single phone number within one minute, you will reach the default frequency limit. If you attempt to send more messages beyond this limit, you may receive an error or the messages might be delayed.
To handle higher volumes of SMS or to customize the frequency limits based on your specific needs, you can apply for a higher quota or adjust the settings through the Tencent Cloud console.
Tencent Cloud offers flexible options for managing SMS quotas and limits, allowing businesses to scale their messaging capabilities as needed.
