Which Unicom card is the number to which SMS call is transferred?

There are two ways to set up call forwarding for mobile phones:

1) Enter the mobile phone call forwarding menu, select a call forwarding type, then select "Start" and enter the number to be forwarded.

2) Settings are made by means of mobile phone dialing:

Unconditional transfer: **2 1* transfer number #; Shut down or not transfer money in the service area: **62* Transfer number # #; No answer transfer: **6 1* transfer number #; Busy transfer: **67* transfer number #.

Tips: Before setting up call forwarding, you need to confirm that the mobile phone card has the corresponding forwarding function.
