What do the short messages from 10086 mean to test macro variable 1 and macro variable 2?

I just received it, too I don't know what happened. Seek an answer

Just called 10086 again, saying it was a system emergency. Let me wait two hours to make a phone call.

Then the customer service lady sent me a client, which can check the phone bill, GPRS and so on.

I don't understand where!
