Downloaded a desert island survival game. I need to increase my Google account, but after a long time, the verification failed and I received the verification code.

It may be due to the following situations:

1. The mobile phone’s short message storage is full. The SMS storage capacity of mobile phones is limited. If you do not clear the received SMS messages in time, you will not receive subsequent SMS messages. It is recommended to delete the SMS messages and try again;

2. Your mobile phone If the phone is not turned on for a long time or is in a place with poor signal for a long time, the text messages sent to you will become invalid due to expiration. It is recommended to try another place; (The valid time of the verification string is: 20 minutes)

3. It is related to the local gateway. Due to the large volume of local text messages during some periods of time, the SMS center is busy, and text messages may be affected, delayed or lost. It is recommended that you change the time period and try again later;

4. It is related to the operator's SMS platform. There are individual failures (ordering inconsistencies occur)
