Generally speaking, it takes 3- 10 days for online channels to issue cards, and 2 weeks for counter applications. ICBC's telephone call back occurs during this time.
First, remember the application materials, it is best to take one with you, and keep more important matters in mind.
Second, say hello to colleagues in the company in advance. The company's fixed telephone number on the application form is the most frequently visited, so you need to say hello to the person who answers the phone in advance.
Especially for applicants with large companies, the bank will probably not make a phone call according to the fixed telephone number you wrote, but check the company telephone number by itself. In case the bank calls, the colleague who answers the phone just doesn't know you, and your application is basically hopeless.
The fixed telephone provided is a friend's, so you should say hello to your friend in advance.
I hope my answer can help you. I wish you a happy card.
