Sender ID and number filtering restrictions

Mobile operators across the world use number filtering and protection rules to protect their customers from unwanted text messages.

Some mobile operators filter text messages that are sent using alphanumeric or numeric Sender ID. In these cases your Sender ID is changed to a random number in order to ensure delivery. This is called number filtering. Please note, recipients will be unable to reply to your texts if this happens.

Number filtering makes it impossible for your recipients to reply to you. However, in most cases your messages are still delivered.
