This is the SMS service number of China Merchants Bank Credit Card Center for China Mobile mobile phone numbers. There is no problem with the source of the number. The card center does not use the 95555 short signal segment. This is a "holiday quota" improvement service launched by China Merchants Bank Credit Card Center every year for the peak consumption seasons of Christmas and New Year's Day. This temporary quota is valid for 30 days after the application is successful. Before 2009, about 40% of the "holiday quota" would be automatically raised when holidays came. But now, in order not to make people feel that you are forced to "raise the quota", the bonus is raised after you reply to confirm.
