Can Unicom secretarial service receive short messages?

1, the secretary function of China Unicom is based on the call forwarding function, and it cannot be realized without the call forwarding function on the system.

For example, if you transfer number A to number B, then both numbers have call forwarding function, otherwise it is impossible to transfer.

2. In the past, Unicom's letter service was blocked (Unicom's letter service: third-party cooperative charging short message service, and spam messages), but it was not received.
