Parental control - block a phone

[AndyT10]

I have a 12 and 15 year old boys. How can I block their phones from being used when I want. I have family link but it's not enough and one is android and the other ios. 

Is there a way to simply disabled their phones or sim cards remotely?

Hi @AndyT10 

Welcome to the Community. 

Family Link is a good shout, as this should give you control over locking/unlocking their devices as you see fit. 

When I've used this feature myself, it's worked instantly with no issues. Have you tried doing this before? 

Speak soon,

@AndyT10  Upon setting up the iPhone you can set it up for a child and with that you can put time limits on it, I’m pretty certain android has something very similar
