Adding children's account for existing group

[Altrux76]

I already have a spare SMARTY SIM, which I want to activate for my son, to then join our existing group. I seem to be going round in circles forever: he can't join the group until I activate the SIM, and I can't activate the SIM because he's under 16. What's the solution here - just create his account and activate with a fake DoB?

I just registered my son's SIM in my name. Trouble with making up a date of birth is should you ever need support in the future and you forget the date you gave, you risk losing access to the account and/or the number. Same should SMARTY ever decide to ask for proof of ID.
