I am a mobile card. Why can't I use it to go to Hong Kong?

If it's China Mobile, you need a global card first, and then you need to open an international roaming service before you can come to Hong Kong. Compared with the mainland, the economic activities of Hong Kong, Macao and Taiwan are basically international, and countless people have been cheated on this point.

I suggest you go to 7- 1 1 or OK convenience store to buy a people's stored-value card. It is very cheap to make phone calls and send text messages, especially when you call back to the mainland, you are free of long-distance charges. If you don't call, buy a One2free network card, so you can use WeChat, so you can communicate and not lose contact.

I hope I can help you.
