# Messenger on multiple devices

# Messenger on multiple devices

As we do not cache received messages for security and privacy reasons, Messenger can only be used reliably on one smartphone. It is therefore possible that incoming messages are only displayed on one of your smartphones. Sending is nevertheless possible from all set-up smartphones.

We recommend that you only use the Messenger function on your main device.
