Why don't you send text messages when the internet traffic runs out?

If you have a package, such as the 30M package in 5 yuan, Mobile will remind you when you still have 3M, but because the system is busy, you will generally not receive this reminder. 10086 will tell you that it is the system. You can send a short message to 10086, or log in to Monternet to check your traffic usage. However, 1 is not available until the traffic exceeds 1M, which is not too expensive, but much cheaper than before.
