How many calls and SMS messages per second can my Twilio account make?


Each Twilio account can make 1 outgoing call per-second. If your account needs more, please contact our sales team about options for higher limits.

SMS via Long Code

Each Twilio SMS-enabled long code (a regular 10-digit number) can send 1 SMS message per-second, per-number. Unfortunately we are not able to adjust this rate limit. If your application requires a high volume of outgoing SMS, we recommend using an SMS short code.
For more details, please read “How quickly can I send SMS messages“?

SMS via Short Code

Each Twilio short code can send up to 30 messages per-second. If you need to send more that 30 messages per-second please contact our sales team.
