Keeping your SIM safe

Holds and limits#

The safety system can apply new_recipient_cap, recipient_cap, content_cap, link_restricted, bulk_hours, carrier_cooldown, device_hot and platform_hold. The hold reason is returned with the message so the caller can explain the delay and choose a safe fallback.

A quarantine pauses risky traffic while the account or channel is reviewed. Do not bypass quarantine by rotating recipients, keys or devices.

The safety score combines recent failures, volume, recipient novelty, content signals and operator or carrier feedback. Reduce pace, use known consenting recipients and wait for the cooldown instead of forcing delivery.
