Since coming to China, I've been slowly learning the various systems out here. One particularly useful thing I've worked out is how to use China Unicom; specifically how to enable GPRS and how to switch their support number into English.
I've provided them here for public reference:
Text "KTGPRS" to 1065581234.
Accessing Account Balance in English:
1 0 1 3 0 8 9 + 3 + 4 + 2
It should be noted that Unicom's interpretation of GPRS does not support internet or email so it's rather useless. I am planning to switch to China Mobile soon…
