EC200U-CN Dial up error

Dear sir,

We have developed one 4G dev board based on the EC200U-CN module.Except dial up connections ,module is working as expected.Drivers are also installed properly and all usb ports are available in windows 10.

Firmware version: EC200UCNAAR02A01M08

When we try to connect using dial up ,it gives the following error.

We have been struggling with this issue for the past 2 months.It will be very helpful if we get early support on this issue.

Dial up error is : error 633


Hi pritesh,
Our EC200UCNAA module do not support PPP feature on R02A01 version, but our latest version has support this feature, i will send you the FW via email, pls check your email, thank you.
