I want to use a mobile phone with my mother, but I hope we can manage each other in the mobile phone. Can you do it?

1: That's a dual card dual standby mobile phone. It doesn't matter if you use a number and your mother has a number, but it's really untrue!

With a smart phone, you can set "confidential information" and "confidential phone book". All your information is set to "password relationship, secret". Use your password to move all messages sent to you by others to the short message storage box. I think it's best for your mother to take the mobile phone and put the number that might call you into the "blacklist", because it's for you, but your mother answered it! Or "call forwarding". I hope it helps you.
