# SMS

> Explore Hypersender MCP tools for sms.

| Tool | What it does |
| - | - |
| `send_sms`, `schedule_sms` | Send or schedule a message. |
| `list_sms_messages`, `list_sms_threads`, `list_sms_heartbeats` | List messages, conversations, or phone heartbeats. |
| `update_sms_thread` | Archive or unarchive a conversation. |
| `delete_sms_message`, `delete_sms_thread` | Delete a message or conversation. |

For scheduled SMS, confirm the time in the sender phone's timezone. A provider accepting a message doesn't necessarily mean it was delivered.
