Excellent For Smart one customers only. Works perfectly and can get rid of those pesky calls from loan agencies/ banks. You must contact Smart one for it to work

Not Free This app is not technically free. It's free to download but when you first use it a message pops up saying It's for use with some subscription you have to pay for. Uninstalled.
