Is there a family number service on mobile now?

Yes I don't know if you want to do the family number service by phone or SMS, but you can do both ~ There are corresponding packages in the M-Zone ~

If it's a phone call, go to Happy Space. You can set two family numbers. Among them, the caller is 1 minute, and the called person is 5 points. But if you want to answer for free, go and run a green campus or something ~

If it's a text message, use a new music package. You can also set two family numbers. Sending text messages between family numbers is free and unlimited ~ I'm using this service now ~

I hope I can help you ~
