There are many kinds of problems. I personally remember that the main reasons are probably as follows.

1. Call ICBC and ask whether overseas payment has been enabled. Usually, in order to avoid some foreign fraud or maxing out your card with fake cards, overseas payments are usually closed. You need to call the staff to open it for you. It is recommended to ask them to close it after the activation is completed.

2. Address problem. Your bank statement address must be consistent with the bank statement address you filled in when registering. This is easy to do. Since the address you left with the bank is in Chinese, you can fill it out in Pinyin when you sign up. There is no default address for bank statements. You can call customer service and ask them to send you a bill, or change the address you left before. It must be consistent with the billing address you filled in when registering. This is a must. If you do not fill it in, you will not be able to register successfully. .

3.pin number and the like. You just need to check these trivial things a few times.
