My traffic speed suddenly slowed down. I consulted the mobile customer service lady. She checked and said that my mobile phone number is not limited, but the network speed is basically around 50.

If your traffic usage is limited, it is impossible to restore the network speed by opening a general traffic packet, so you need to open a network speed recovery packet. In view of the differences in business regulations among provinces, please consult local 10086 in detail. Take Henan as an example: 5 yuan 1G replies to the network speed superposition package, and 5 yuan 1G replies to the domestic traffic. After the flow is used up, it will be automatically renewed, which is valid in the current month. You can't unsubscribe in the current month, but automatically unsubscribe next month. Henan Mobile users can edit SMS 3530 and send it to 10086 for opening.
