What if the traffic packet doesn't work?

According to the information you provided, please confirm that if you are handling a package in the province, no matter where you are, the package ordered in the province can only be used in the province where the number belongs, regardless of the location of your mobile phone. If you need to use the number outside the province, you need to apply for a domestic traffic package. If you can't use 4G for the above reasons, you can try to turn it off, turn it on and restart it. If it still doesn't work properly, you can check whether the default setting of mobile phone-mobile network-mobile data options-voice and data view is 3G. If so, you can choose 4G. Because the specific path of each mobile phone model is different, the actual use method of your mobile phone shall prevail. Please check whether the traffic speed limit or traffic upper limit has been reached. If you still can't use 4G, you can't rule out that it doesn't meet the use conditions. At present, China Unicom's 4G network needs to meet the following conditions:

1) The mobile terminal supports Unicom's 4G network.

2) The current location has been covered by Unicom's 4G network.

3) use Unicom USIM card

4) The number is enabled for 4G Internet access (can I send short messages? KT4G？ 100 10 applies for opening, and the opening takes effect)

If it can't be used if the above conditions are met, you can contact the local manual customer service to find out whether the base station in your location is out of order and follow the instructions.
