Why can't I get the SMS of verification code from China Ping An Life Insurance Company of China Insurance Company on my iphone6?

Confirm whether the mobile phone is in the signal area and whether the number of the SMS center is correct in the SMS settings.

2. The 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. ?

3. 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. Suggest to try another place;

4. 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. ?

5. It is related to the SMS platform of the operator. There are individual faults, is it true that mobile phone security software restricts SMS service?

6. Determine whether the number entered on the website of the mobile company is the number currently used, and whether it is entered incorrectly.
