Reporter investigation

Multi-charge for call cutting

However, China's "communications industry standards", there is no call time long division billing. Moreover, this bill shows that the 7 times more than 5 minutes of the call, not once is completely according to the so-called standard that every 5 minutes split once to accurately billing. February 10 20:09:41 to 21:00:13, tail 6499 of this cell phone has a 50 minutes and 32 seconds of the main call, if all according to 5 minutes division billing, should Form 10 5 minutes and a 32 seconds of call billing records, as long as the 51 minutes of the charge on the line. However, the detailed list of charges shows that the call was divided into 7 5 minutes, a 5 minutes, 10 seconds, 2 5 minutes 1 seconds and a 23 seconds, such as 11 billing, was deducted in accordance with 54 minutes, thus, mobile phone users only this one phone will pay more than 3 minutes of the bill.

The error rate is ridiculously high.

Reporter investigation found that China's "communications Industry standards" stipulates that the error rate of mobile phone network is not more than one out of 10,000. A call or SMS, GPRS traffic, such as Billing Records is a single, that is, in 10,000 billing statement, can not appear more than 1 error messages. and tail 6499 of this cell phone, in February, the detailed list, there are 162 call billing records, of which there are 7 error statement, billing rate of up to 4.3%. A month like this, there are 7 error statement, it should be a very small probability event, it is hard to believe that this is the telephone exchange billing system itself Error record.

Reporter noted that because of the length of the call by irregular split billing, and is more than the number of mobile phone users will not stop Mr. Huang.
