Adding SIM but using same email address

[RonaWil_2823884]

I want to add my kids to a group all under my existing email address/account.  I have spare existing SIM cards to use.  Going round in circles trying to do this in a way that allows me to use the SIMs I have (not having to post for new ones) or have to set up email addresses for them.  
Has anyone been able to do this please?

Adding them as 'nickname' accounts should work.
