I sent messages from approved Sender ID, and the message was received from another Sender ID

If you have sent a message and it was delivered with another Sender ID this means that the used Sender ID is blocked by the destination network.
In such cases we send your message with a default Sender ID to ensure the arrival of your messages. For example: Sender IDs to Qatar should be approved by the network to allow the messages to be sent to mobile numbers, any messages that sent from Sender ID that is not approved will be delivered with our default Sender ID "SMS Alert".
