Stops mobile data for one of your customers — for someone who has used up what they paid for. Calls and texts keep working; use the suspension endpoint to stop the whole line.

The call returns once the change has taken effect at the network, so a 200 means the data is genuinely off. Nothing here is queued for later.

Stopping data that is already stopped returns 409 and changes nothing. Our own automated processes never undo a stop you made — only DELETE on this path does.

Not every market offers stopping data on its own. Where it does not, this returns 422 and nothing changes — the Markets page in the documentation lists which is which.
