My mobile phone always receives messages from ICBC messengers, saying how much balance is left in my card? What's the problem?

This is the balance change prompt service of ICBC messenger. When your account balance changes, it will send a short message to remind you, so that you can better understand your card usage. If you don't want to receive this message again, you can call the customer service hotline to apply for cancellation, but this service is quite convenient and free for the time being.
