Unsubscribe from wireless SMS.

This may be due to the following conditions:

1, SMS storage is full. The short message storage capacity of mobile phone is limited. If you don't clear the received text messages in time, you won't receive the follow-up text messages. It is recommended to delete the message and try again.

2. Your mobile phone is not turned on for a long time or in a place with poor signal for a long time, which will make the short message sent to you invalid because it has expired. Suggest to try another place; (The validity time of the verification string is: 20 minutes)

3. It is related to the local gateway. Due to the large number of local short messages in some time periods and the busy short message center, short messages may be affected, delayed or lost. I suggest you try again at another time.

4. It is related to the SMS platform of the operator. There are individual failures (inconsistent orders)
