Why can’t the Postal Savings Bank mobile phone receive balance text messages?

First, have you changed your mobile phone number? If so, you need to go to the counter to change the SMS notification number of your bank card.

Second, if not I have changed my number. If there are no text messages for balance changes now, then go to the counter and tell me that I can't receive the text message notification of the balance change of my bank card and ask for it. You need to explain to him whether it has been a long time or just recently. Not received.
