Why did the message sent yesterday arrive today?

Why did you receive yesterday's message today?

1, the phone is turned off or not in service area, which will affect the timely reception of short messages. Generally, SMS will be stored in the operator's system for 48 hours. When the mobile phone is turned on within 48 hours or returns to a place with network signal, the system will automatically forward the short message again. If it exceeds 48 hours, the message will be invalid.

2. If this happens frequently, check whether there is not enough space in the SMS memory. If the space is insufficient, it will lead to the inability to receive new information in time, and some or all of the information can be deleted.

3. If there is no problem, you can change other mobile phones for testing. If other mobile phones are normal, it is recommended to test them. If it is still abnormal, it is recommended to go to the business hall to test the mobile phone and card.
