Why did the postal gold card suddenly have no text messages these two days?

The reason why you can't receive the text message may be that the system is out of order these days, or your mobile phone is in arrears, or your gold card has been downgraded (the gold card of the Postal Savings Bank will be re-rated every quarter, with an average quarterly balance of more than 6,543,800 yuan (inclusive)). Gold cards are generally used for free SMS, so SMS can't be received once it is downgraded.
