China Mobile's traffic plan exceeded that of 60 yuan, and then the customer service sent me this short message. Who can explain what this means? Is it possible for me to avoid it now

If you use the optional package of traffic, the domestic traffic will be 0.29 yuan/m after exceeding the package; If the usage of 4G exceeds the tariff, the domestic traffic tariff is 60 yuan/1G (less than 0.29 yuan /M in 60 yuan). That is, the out-of-package communication fee is charged at 0.29 yuan /MB first, and it will be suspended after reaching 60 yuan, and the out-of-package traffic can be used to1GB; Free of charge; After 1GB traffic is used up, follow the above rules and so on. If you order the peace of mind package, the domestic traffic charges are 10 yuan/100M and 60 yuan/1g (if it is less than 10 yuan, it will be charged at 0.29 yuan /M).
