Someone else's bank card SMS notification reserved my mobile phone number, which brought me trouble. How to cancel? The bank counter refused to handle it. I want to make a complaint.

If you complain, you can call your bank's customer service number, and your mobile phone number should be recovered and reused. In this case, banks and mobile companies can't handle it, so they can only block bank card messages.

1. Reserved telephone and its functions: The reserved telephone refers to any one of the mobile phone, home phone, work phone and emergency phone registered by the customer at the bank for the last time. Most of them are reserved mobile phone numbers, and the security information can be verified by receiving the verification code through the mobile phone, which is convenient for self-service banking. Function: SMS can verify fast payment, and online payment can be made through SMS verification without opening online banking. It is beneficial to reduce the operation steps in the online shopping process and improve the security.

2. Telephone card: Making a phone call is a communication way for people to contact each other. People who are thousands or even tens of thousands of kilometers apart can contact each other by telephone (especially by long-distance telephone), which not only saves the fatigue of long-distance running, but also saves time and travel expenses, greatly improving work efficiency. On June 2, 20021year, the Ministry of Industry and Information Technology and the Ministry of Public Security issued a notice on "Cleaning up and Rectifying Fraudulent Phone Cards, Internet of Things Cards and Related Internet Accounts according to Law".

3. Magnetic card: Magnetic card is a kind of magnetic card that replaces cash to pay telephone bills. It is a "key" for people to communicate. It's about the size of a business card and easy to carry around. After purchasing a magnetic card with a certain face value, users can make local calls, domestic long-distance calls and international long-distance calls by inserting the magnetic card into the telephone. The telephone charge is deducted from the stored value of the magnetic card. When the stored value of the magnetic card is 0, the magnetic card is invalid and needs to be replaced. It is free to make special emergency calls such as 1 19, 1 10, 120 with a magnetic card. After the call, the inserted magnetic card will exit as it is, and the face value on the magnetic card will remain unchanged. In fact, you don't need to insert a magnetic card when making these free calls. After picking up the phone, just press the "emergency call" button on the phone and you can dial the phone like an ordinary phone.
