There are specific instructions in 2 and 3 in the document, and we check according to our actual situation.

Second case:

Because this application is tested by overseas applications in China, we also have to consider whether the scenario meets the relevant conditions that overseas applications need to meet when they are tested in China. The specific conditions are as follows:

For overseas applications to be tested in China, the following conditions must be met:
1. The test machine should be an overseas device, and the network environment should be the network in the corresponding overseas area. In the case of using WIFI, it is recommended not to insert a SIM card, otherwiseMake sure that the SIM card is the SIM card of the corresponding region;
