How do i send SMS using SIMcom A7670C GSM Module with the alphanumeric text instead of my actual number

I want to send SMS to a user with the Alphanumeric text instead of my phone number in SIMcom A7670C GSM Module. I have tried PDU mode but still getting error.

I want to try to send SMS like the below format

Example

Sender: BLUDRT

Message: Your Shipment is Delivered.

But i am getting the below format

Actual Message

Sender: +(Country Code)(My Phone Number)

Message: Your Shipment is Delivered.

I have tried PDU mode but it is giving me error.

Answer

This is not supported by SMS nor PDU and therefore it is useless to even try.
Ordinary one would rather send AT commands as this is a modem -> wvdial.
