When you set a delay between messages, that delay is the minimum waiting time. In real use, the actual gap between messages can be a bit longer. Here are some reasons why:
- After one message is sent, the system still needs to finish tasks like checking status, updating lists, and preparing for the next one.
- If your message includes media (like an image) it takes longer to upload and send.
- Your phone, network or browser might be busy or slow, causing extra delay.
- The carrier may queue your message if there is heavy traffic or other senders using the network.
