You can send MMS message requests to Plivo at a rapid rate, as long as you don't surpass Plivo’s default API concurrency limit of 100 simultaneous requests. However, there are limits to how quickly Plivo can send messages to carrier networks.
Plivo has two types of rate limits for sending MMS messages: at the long code phone number level and at the account ID level.
- Long code phone number: A rate limit on each Plivo long code phone number keeps you compliant with carrier regulations and reduces the risk of messages getting rejected by carriers.
- Plivo account ID: A rate limit on each unique Plivo account or subaccount protects our network performance and helps to ensure fair service across all customers.
