Will I get a refund if I unsubscribe from postal SMS?

1. If you haven't added SMS service at the counter, you can unsubscribe from SMS service at the front desk with your ID card and passbook.

2. As you have added a one-year one-time payment account change notification SMS service, you should pay 3 yuan every month and 36 yuan all year round. As you have chosen one-time payment, you will only deduct the SMS usage fee from 30 yuan. If you really want to return it, you can only go to the post office to find the leader in charge of SMS business. In principle, there is no refund, but if you really don't handle this business, how much the post office is willing to refund you depends on your local situation.

I hope I can help you.
