How to open the flow? (I said it can be used all over the country, not just in this province)

Go to the mobile business hall to send text messages. Different charges will send different contents, such as 5 yuan 30 MB, which seems to be 5g to 10086. However, in order to be accurate, you still have to call 10086 and press 0 to ask the manual station. She will tell you the right way, and it's quite cheap now. It will take effect next month after processing. I don't think I can get in by hitting the manual station now, because it is.

Cangzhou cards seem to be all over the country now. I used Cangzhou card in Tianjin, and it should be like this. Yes, that's what I did when I did it, and it shouldn't change now, so it doesn't matter whether it's inside or outside the province.
