Nice reliable product with no dropped calls or audio issues. I use to call people internationally when I am on the go over LTE or WiFi.

DialHard has been great for me and the guy running it is responsive and cares. I feel the most looked after by an app ever.

For now it is great. Not much issues. Someimtes the call is dropped without even starting. Not sure it is from the number or what. It has happened 2-3 times, so I guess it is because of the number. The main issue I faced is the call drops when you have to select menus from dialpad. Let's say the call asks to select a menu for language, you select a number, then another menu option, then another, then another. I think after 3rd or 4th the call was dropping automatically. It happened only once though. In general, I am very happy with DialHard. For an upgrade, it would be great if user can copy/paste number to the dial.
