Yunnan Dehong China Mobile SIM Card
Dear friends, I found that the China Mobile system is updated in 2 to 8 hours. That is to say, before the system is refreshed, neither the traffic nor the phone bill will be deducted, and if the traffic is not used up and is changed to a smaller package, the excess money will be returned (for example, the package is 50 yuan for 500 MB, but 140 MB is used, and the package is changed to 30 yuan for 280 MB, because the traffic is not used, so 20 yuan will be refunded). I checked the data rate at 1 am on the 1st. The data rate has been updated, but the data rate has not been deducted! I would like to ask you if there is any way to crack (brush) it. Thank you in advance!
