Read messages

Retrieve received messages using the dedicated SMS API for your number.

Transfer ownership

The recipient confirms the handover. The original API is revoked; past messages and payments stay with the original account.

Ownership transfer rules

Only eligible active numbers can be transferred. The recipient must confirm before the request expires. After completion, the original account loses access, export, renewal and management permissions, and the original SMS API is revoked. Historical messages, purchase and payment records remain with the original account. This is an account ownership handover, not carrier number porting.
