How to cancel the monthly SMS subscription service?

Hello, if you want to do it yourself, you can edit the short message "" and send it to 186. You will receive a reply message telling you which monthly subscription services you have customized, and then reply to the serial number of the service you want to cancel, which will take effect within 24 hours. You can also edit the short message "" to 186 to cancel all monthly subscription services at one time. You can also ask the customer service representative to cancel it manually by the owner's name or cancel it at the automatic desk by the password. I hope my answer can help you.
