My card and my dad's card are combined into one, and the phone bill is synchronized. I use the phone bill to buy traffic, and the mobile phone will send messages. Can he receive the message?

If you use Unicom number, it is suggested that you can customize the flow of your card in the following ways, and this opportunity will receive SMS:

If your card is a secondary card, log in to the telephone hall with your mobile phone number and customize a traffic package yourself. After successful customization, SMS will be sent to your mobile phone, and the traffic is also for your mobile phone and cannot be shared with the main card. But after the monthly statement comes out, there will still be this fee on the account of the main and auxiliary cards, which is your father's mobile phone number.

Reminder: Due to different policies in different provinces, the businesses launched are also different, subject to local customer service or business hall consultation.
