My ICBC messenger didn't change the number or cancel it. Why can't I get the message?

If it is not received for only one day, it may be a system problem, that is, the so-called transmission delay or no transmission. In this case, you can dial 95588, 2 for manual service and 5 for business consultation. Note: Be sure to dial with your own mobile phone number that accepts SMS! In that case, if you call in, you can ask the staff to help you check whether it has been delivered to you. If sent, it may be delayed. There is no way to solve this kind of thing, and there is no need to be serious with the staff. The system is hard to say. If you don't receive it in a day or two, it may be that the service has expired. You can log in to your personal online bank and check the service period in ICBC Messenger-My ICBC Messenger. You can also call 95588 and ask the staff to help you with this operation. If the service expires, it can be renewed by telephone, online banking or outlets. 2 yuan money for each account every month. I hope I can help you ~
