Unicom handled the card sent by broadband, but did not send a mobile phone, but received a short message with the card separated.

The business hall you mentioned is Unicom's own business hall, not an agent. If it is Unicom's business hall, you should consult the staff of the business hall.

However, even if the real card is separated, it doesn't matter. Only Apple can truly realize the machine card binding.

But it is worth reminding that you want to give your mobile phone, but the staff didn't give it to you. Dear, please pay attention to it yourself!
