It's worth a try. However, expect the brokers to claim that they cannot be sure that you're the only person using the phone and therefore, for privacy reasons, they can't share the data.

You can complain to the Irish DPA (because that's where the broker is likely hiding, pro-forma), which will respond within a year or two with a request for more information.

If the broker made the mistake to be domiciled in a location with a more competent DPA or you are willing to drag them to court, you might stand a better chance.
