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
