Mobile phones can transfer calls, but how to transfer short messages, Unicom?

If you want to realize SMS forwarding, I suggest you handle the SMS forwarding service of Unicom. "SMS call forwarding" service provides you with SMS call forwarding service. When you need it (for example, the mobile phone can't send and receive messages normally, or you don't want to be disturbed during the meeting), you can set the SMS call to be transferred to other mobile phone numbers of Unicom.

Note: SMS call transfer scope can only transfer point-to-point SMS calls to other mobile phone numbers of Unicom. It does not support the transfer of point-to-point SMS calls to other operator numbers, nor does it support the transfer of incoming SMS messages from Unicom to other mobile phone numbers of Unicom.
