The mobile phone sent a message saying that you used mobile traffic 18k. What happened?

That is to say, personal traffic has been used 18KB this month.

This is a mobile phone SMS reminder function. The SMS reminder service for mobile data traffic provides free SMS reminders for mobile phone users, data card users and G3 netbook users, which is convenient for users to keep abreast of online traffic usage. It is free of charge and can be divided into SMS reminder of residual traffic and SMS reminder of regular traffic.

SMS reminder of remaining traffic: When the remaining traffic of customers using mobile data is 5M or 0M, or the remaining traffic of netbooks and network cards is 50M or 0M, the system will send SMS reminder.

Regular SMS reminder of traffic: send SMS reminders of traffic usage to customers from 1 1 and 2 1 every month.
