I haven't had a debit card or a platinum card, but I've been sending messages saying how much it cost and the mobile phone card is new.

Well, it still happens from time to time. It's not your fault. The possible reasons are as follows: 1. The customer mistakenly entered your number when reserving the SMS number. 2. The mobile phone number was used by the original person, but it hasn't been used for many years, but he used it to send a message to remind him.

Specific solutions:

1. Go to the bank counter and ask to cancel the SMS.

2. Call the customer service phone of the bank that sent you the text message, complain and ask to cancel the text message.
