EC200U Dual SIM Support

Hi there
I’m going to use EC200U in my project and i need to know if it supports 2 SIMs to interface with or do i need to add an IC to achieve that ?

According to our hardware reference design, the EC200U does not support dual SIM, you can achieve dual SIM by switching circuit

Thanks for sharing details.

I have check the datasheet and found that there is provision of 2nd sim interface.
To use dual sim I need to update the firmware , right? where should I get it?

I have query about dual sim,
is both sim cards are activated continuously like working in our mobiles ?

Updating Firmware
For updating firmware USB is necessary?
Firmware upgrade can possibly be done by UART interface?

Thanks & Regards

What is your current firmware version?
