Can I transfer my mobile phone number to Unicom number? Can you still get the message?

Hello, if there are related services in China Mobile, incoming calls from the mobile number can be transferred to the mobile phone of China Unicom. If someone calls from the mobile number, the mobile phone number of China Unicom can be answered. After successful answering, the basic forwarding fee of the mobile phone number should be charged, and the mobile phone number can receive short messages normally. But whether SMS can be transferred to other mobile phone numbers depends on whether there are related services in mobile.
