I didn't do anything when the SMS was verified by UnionPay payment. Details are as follows.

That is, when someone pays with UnionPay, someone mistakenly enters your mobile phone number and will send you a text message. This can be ignored.

Generally, the number of China UnionPay is not easy to forge, so it should be true.

There are two possibilities:

1, someone opened it with your card.

2, someone else opened it, but wrote the wrong phone number, so it was sent to your mobile phone.

You can contact UnionPay to ask if it can be cancelled.
