Of course you can! Just log into UrbanPro.com, go to 'Account' section, click on 'SMS alerts' tab and then submit your mobile number when prompted to do so. That's it!
Once you do the above, you will receive all enquiries as an SMS on your mobile phone.
You can turn off the service by just following the same steps again to go to the 'SMS alert's page and clicking on the 'Click here if you do not want to recieve SMS Alerts' link.
