 Hello
I need to know if I have Chinese Miracle activation in my dongle
as I wanted to buy 1 year support for my Infinity dongle.
Am I able to work with MTK and SPD chipset phones with the below dongle serial?

Code:

Is this enough to buy:

Infinity-Box/Dongle 1 year Updates/Support Renew, Chinese Miracle-2 included 120 credits

or do I need to buy

Infinity-Box/Dongle software activation for Infinity CDMA-Tool, Chinese Miracle-2 and 1 year support included 200 credits
