Unless you were using an online data backup service such as what Google provides for Android phones or a third-party backup program, unfortunately your data is gone along with the phone. Cell providers usually have some sort of contact backup service but you would have to have already been subscribed to and using the service to retrieve your contacts and download them to a new device. Apple has backup services similar to Google's Android phone backup but if you had an iPhone you would have needed to already be subscribed to the service to have any data available for your new device. I wish I had better news for you.
