If there is no fixed telephone, you can fill in the fixed telephone at home or at a friend's house.
The telephone number of the company must be truthfully filled in. Generally speaking, you need the landline number of some units, which can better reflect the stability of the applicant's work unit. If the company doesn't have a fixed telephone, you can borrow money from relatives and friends, or you can install a fixed telephone yourself and transfer it to your mobile phone. In short, the company phone number must be filled in, and it must be a fixed phone number. Remember, you can't just fill in your phone number when you apply for a credit card online. When the bank pays a return visit, the first call is the company's phone number. If you find that the information is wrong or no one answers at all, the bank will judge that there is something wrong with your credit and refuse to take the card.
