Stops mobile data on one line — for a customer 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.

Data is stopped against the data pool the line draws on, so a line in none of your pools returns 422. Not every market offers stopping data on its own either; where it does not, this returns 422 and nothing changes — the Markets page in the documentation lists which is which.
