1. Open international roaming on your mobile phone, call the customer service number of ICBC 95588, and add the area code of China and the city area code before the phone, such as Beijing +0 10 and Shenzhen +0755.
2. If your country or region supports international calls, you can directly call ICBC's international customer service number 86 1095598 or +86 1095598, and then follow the voice prompts. It should be noted that if international roaming is not enabled on your mobile phone or your country or region does not support international calls, then you can't dial 95588 directly with international calls.
In addition, the bank's manual customer service may be busy during busy hours. I suggest you call ICBC's customer service number first, and then call to avoid missing important business contacts.
