On August 23rd, the Postal Savings Bank sent me a text message, but I couldn't find it.

The system is delayed or there is no balance in the card to pay the SMS reminder service fee. There is no SMS reminder in the postal savings bank card because the system is delayed or there is no balance in the card to pay the SMS reminder service fee. If this happens occasionally, it may be caused by network delay and will be sent to your mobile phone later. If you haven't seen it for a long time, you need to bring your ID card and bank card to the designated bank window for consultation. The staff will help you find out the reason and then tell you the solution.
