I bought the national debt with my ID card. Why is there a text message on my wife's mobile phone?

Because of the identity information, there will be text messages on grandma's mobile phone.

1. The national debt voucher is bound to the identity information of the purchaser, and the mobile phone number registered when purchasing national debt will receive relevant SMS reminders.

2. In addition, when investing in treasury bonds, we should also pay attention to observing relevant national laws and regulations and strictly control the amount of investment.
