Temporary block my teenager phone contract

[JEM07]

Hello, does anybody know if you can put a block on a contract with sky? Its my teenage son, his behaviour is shocking lately and I don't want him to have use of the phone I pay for and he will not hand it over.

Any help greatly appreciated,  obviously I don't want to stop paying it just block him from being able to use it so I don't have the argument of trying to physically take it.

Thank you

No, Sky do not offer such a facility.

You should investigate whether the OS provides parental controls.  e.g. https://support.apple.com/en-gb/105121
