My Tencent King card has a lot of traffic. In the past, it was very fast to use 4G for mobile phones, but now it is very slow to use new mobile phones. I heard that it is limited. Why?

In order to follow the principle of fair use of traffic, the system will automatically turn off the data function when the total amount of free and non-free Internet access of Tencent Dawang Card reaches 40GB in that month. If you need to continue surfing the Internet in the current month, you can call the local Unicom customer service phone number 10 10 to apply for unsealing. After unsealing, you can use it normally, and you can also provide 4G high-speed Internet access service. However, the free service in the current month is charged by the day, and the free service will be automatically restored in the next month 1.

If the network speed was normal before and slowed down after changing the mobile phone, first confirm whether the mobile phone supports Unicom's 4G network (Unicom's 4G network standard: TD-LTE/FDD-LTE) and whether it is currently using 4G network. All the above conditions are met, so you can empty the phone cache before using it.
