Why can't my mobile phone receive short messages from others immediately, but it takes two or three minutes or even ten minutes to receive them?

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

First, the network system is busy. I suggest you try again another time.

Second, because of the mobile phone, you can restart the mobile phone or change it to test it;

Third, 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. It is recommended to start again after paying.
