What does it mean when the message "Sending on hold" appears when sending a text message?

It is because the network cannot contact the target mobile phone and the message cannot be sent temporarily. At this time, the target phone may be powered off or out of service area.

The information report we received is the report given to us by the mobile phone service provider. Information sending will be delayed only when the two numbers are from the same service provider. There will be no transmission delays when China Mobile sends it to China Unicom, or when China Unicom sends it to China Mobile, unless the network is blocked or malfunctions.

Thank you!
