Why bother
Downloaded it to try out. No mention on app info that you need to go to their website to get your efax number from them and a pin.
When you try to register, you are stuck in a infinite loop of providing your faxing location.
Read their info - says free for 30 days but they will start auto charging your credit card immediately after at $12.49 a month.
Really $12.49. Other programs offer 10 cents per page or 99 cents a fax. Real turn off. I refuse to deal with companies that tell you that they are just going to help themselves to your money.
Run away.
