Shandong Unicom SMS test

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 it to test it;

3. Long-term shutdown or out of service area;

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

5. The mobile phone is out of service, so it is recommended to pay for it and turn it on again.

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