What is the delay in receiving SMS by mobile phone?

There may be the following reasons for the delay in sending and receiving SMS:

1. The network system is busy. I suggest you try again next time.

2. Because of the mobile phone, you can restart the mobile phone or change the mobile phone test;

3. Long downtime or out of service area;

4.SMS inbox and outbox are full. Please clean them up and try again.

5. The mobile phone has been stopped, so it is recommended to pay for it and start it again.

The above reasons have not been solved after being eliminated. Please contact 100 10 for manual customer service.
