Activating sim for under 16

[Christo_3153051]

I have just joined and bringing over my number and 2 children under 16 numbers. I set up a group plan and included them. Have activated my sim and waiting for number to come across. Are the under 16 numbers being activated at the same time? Or do they need to set up accounts?
