How to cancel Aihong Technology's texting all the time?

Aihong Technology has been sending short messages to cancel as follows:

1, reply to the unsubscribe instruction in the SMS. Usually, SMS will prompt you to reply to instructions such as "TD", "T" and "unsubscribe" to cancel the subscription.

2. Call customer service. You can check the customer service phone number on the website or official channel of Aihong Technology, communicate directly with the customer service staff and ask to cancel the SMS service.

3. Block SMS in the phone settings. If all the above methods have no effect, you can choose to block the SMS sent by this number in the settings of your mobile phone, so that you won't receive SMS from this number again.
