And also you need GPRS Connection on your mobile to get the certificate and key.

  • Now what is XSteveDore Express?

It is present in the above rar file. YouGet your Certificate Automatically from
your Phone by installing XSteveDore Express.
XSteveDore Express is a new application from OPDA and it lets you check, 
acquire and update your certificate and key file straight from your device. 
The language of the software is Chinese. But do not panic for this. It is real easy. I have also done it within 5 min even for the first time.
But note this cautiously, you will have to request, acquire and download the certificate and key file within the first 2 hours of the installation. After 2 hours, this application is useless in terms of obtaining certificate and key file.
