I sent a text message with Unicom card, and the mobile phone display number does not exist. Why?

Unicom card, whether sending short messages to Unicom or mobile, can be sent directly without adding other numbers. Just try it. If this is the case when texting all mobile phone numbers, you can call the customer service hotline directly. If it is a mobile phone number, it may be the other party's number.
