How can I receive a text message when my mobile phone number is not bound?

If the mobile phone number is not bound with a bank card, you can still receive SMS. The main reasons are as follows: 1. You registered banking software: although you didn't use this number to handle bank card business, you may have registered some banking software with this number. When you register the banking software with your new number, the bank will get your number information, and then you will find that there is no bank card of your own bank under this number name. At this time, the banking system will automatically send you a text message, prompting you to go to the bank's business outlets to apply for a bank card. In fact, this often happens because bank staff also have performance requirements. They will check users who have registered banking software. If they don't apply for a bank card, they will send a text message asking them to apply for a bank card.

2. The former owner applied for a bank card. In fact, another reason is that you are not the first user of this number, and this number has been used by another person before. The former owner used this number to set up a bank card, and this number was reserved in the bank card, so the bank will send a text message to this number. When the former owner stopped using this number, he went to the business hall to cancel it, but did not change the reserved number of the bank card in the bank, so the bank will still send a text message only to this number. This often happens, because many people will not unbind this number from the relevant binding software when changing the number, or they may forget it.
