How to complain to China Mobile? I come from Ganzhou, Jiangxi. I have a 120M traffic packet in my card. I use my mobile phone to surf the Internet.

Generally speaking, when you have 5 megabytes of traffic left and are about to run out, you will be prompted by SMS. Looks like you didn't get it. I want to know why I can't get a short message if I can get an Internet signal. Moreover, it is very hateful that even if I receive a reminder message, there is often a time delay of 120 minutes. That's how I exceeded 18 at a time and 2 at a time. I think it's useless to complain like this. Technical things can't be said to be deliberately set by mobile. I am numb. I still remember a focus interview, and Mobile did a little trick on the phone bill timing. In a certain period of time, divide the whole minute into two parts less than one minute, so that you can charge it in two minutes. What other phone fraud, mobile phone built-in charging program, etc. On the other hand, if these messy things can't get some benefits without their internal permission, who will be the big head for whom and go back to work for you where there is no benefit? If an hour exceeds 184, it is also possible to just surf the Internet or download more than 36 megabytes, and the fee will be deducted to 184. I recommend a software called security housekeeper, which is safe and antivirus. It has the function of traffic statistics, and at the same time, it can set the upper limit of online traffic, and automatically disconnect the network when it reaches the upper limit.
