Xuexin.com SMS is limited to 24 hours. What should I do?

2. change your mobile phone number to register.

If you just can't get the text message from Xuexin.com, there may be the following reasons:

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

2. If your mobile phone is not turned on for a long time or in a place with poor signal for a long time, the short message sent to you will be invalid because it expires. It is suggested to try somewhere else (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 later.

4. It is related to the SMS platform of the operator. There are individual problems.
