I want to cancel the subscription of China mobile website for free SMS.

Hello, I want to give you some advice based on my experience.

First of all, you can send 0000 to 10086 directly on your mobile phone (SMS is free), and then the system will reply you with a message about which SP services you have ordered to see if there are any services you have ordered. If yes, reply directly to the serial number in front of the service, and then send 000 to 10086 four hours after cancellation to see if the subscription is cancelled successfully. If you can't find the service you ordered by sending it to 10086, you can directly reply to 10658 105020 to cancel the operation. If sending 00000 to 10658 105020 is not successful, you can directly call the 10086 manual station and ask the 10086 customer service representative to help you operate or submit it to the background for further processing.

Ha ha, for reference only, thank you!
