I want to use EC200U for two purposes simultaneously - GPRS data streaming in transparent mode and sending and receiving SMS for notifications. I prefer to use the main UART for data and the auxiliary UART for SMS.
Does this module support concurrently SMS on aux and data on Main

It is not supported. You can add a USB.
Then, what is real use of this port, debug port I have logs can be seen and see the state etc. In real application, what is use of this aux port?
The auxiliary UART is mainly used for monitoring the boot log of the module, or for outputting GNSS logs (you need to configure it via USB)
Thanks for the update and clarification. I need some help.
I want to use the STM32 MCU with the EC200 module to send SMS and data in transparent mode for data. Is there any readymade example for both services running in concurrently using the main UART?
I also need latest of this document - Quectel_EC200U_Series_Hardware_Design_V1.2.pdf. It is old, latest 1.3 is available.

In transparent mode, it can only send data and cannot send SMS. You need to exit the transparent mode and then execute the SMS operation again.
