WhatsApp and Messenger offer the option to unsend messages as you can only send messages to other users on their platforms, also known as peer-to-peer messaging. Unlike these apps, we do not control the entire experience end-to-end.
When you send a message using our platform, it is pushed to these carrier networks (like T-Mobile, AT&T, Verizon, and others), which are responsible for delivering the SMS or MMS to the recipient.
Once the message is sent to the carrier network, we have no way to enforce unsending it. The message has left our system and is now in the hands of the carrier.
We understand that the inability to undo sent messages might be frustrating, but these limitations are a result of how our service interacts with carrier networks.
