OPPO received SMS delay.

There is a delay in receiving SMS by mobile phone:

1. I suggest you give priority to switching the flight mode of your mobile phone or restarting your mobile phone to see if it is restored;

2. Under the same network type and environment, compare whether other mobile phones also have SMS delay. If other mobile phones also have this phenomenon, it is judged that the network side is abnormal, and it is recommended to try again after leaving the area for a certain distance;

3. If the signal in the area is poor, such as mountainous areas, elevators, basements and other areas. Cell phone signal may be affected. If the other party sends a short message during this period, the reception of the short message will be delayed due to signal problems.

4. If the cell phone signal is normal, there is SMS delay in any area, which cannot be solved through the above investigation. It is recommended that you bring your mobile phone and relevant purchase vouchers to the nearest official OPPO service center for processing.
