How to refuse Fetion SMS

Hello, if the same number frequently sends you friends' information, but you really don't want to agree, you can edit JH # Fetion number/mobile phone number and send it to 12520 to blacklist the other party. So the other party can't send you flight messages anymore. Sending instructions usually charges a short message fee. If you only send it once, you can ignore it and don't reply to the rejection. Please refer to.
