I've been using this for a few years for calls from South Korea to the U.S. It works great for that, but doesn't work the other direction. Calls will drop occasionally but I just call back. Most of the time works fine with no cost to me or the person I called.
After update, no longer dials US numbers or gives false message that number does not exist despite using the same numbers in OTO for YEARS! Sorely disappointed & looking for alternative. DEC. 14 2019 UPDATE: Took two attempts with support but it's working properly again after some weeks.
"The country you selected is not available currently". Funny for an app that advertises itself as better than its competitors because it's not limited in the amount of countries you can call...
great app, but can't you use phone contacts on this app? i have to remember and manually dial the nimbers already saved in phone contacts. and every time i try to access my contacts the app will just quit. cant do anything.!! please give some feedback asap.
Garbage. It will succeed in making the call but it wont succeed in having any sort of quality. You wont be able to hear a word, just get a vague idea that whoever is on the other line is speaking English. Absolute garbage.
Why this app shows me that it's not updated? I have tried to re-install the latest version many times but it still says it's needed to be updated. In addition I cannot call to the UK number.
This was a great app until they started charging for calls to South Africa. Would be great to know why it's free to call to certain countries and not others
Really worst , huge advertisement in between two calls to lodge, can't tolerate, irritating. Don't use this app!!
Not working, says the mandatory data is lacking and reinstall it, but after trying it more than 3 times it still doesn't work
Can't open the apps " Mandatory data installation failed" error. ~reinstalled ~ not working
Couldn't start the App due to Network error even if I reinstalled several times.
The issue I had was fixed. Thank you. This app has served me well for a number of years.
It works but its not free am using it in korea but somehow it still boost my cell phone bill

On pressing Contacts it crashes on Galaxy S9. Please fix this issue. This is 100% reproducible and a basic sanity issue. Please help fixing asap.
Only available in japan and korea
I'm using this app here in Korea. Whenever I try to call to other country, I hear: "the number you dialed does not exist." Not my friend's number but the connecting number 1600-9316.
I need my money back I just been 49 99 and it said I have zero credit or try to call it doesn't work need my money right now
I hated this app app name is free international call but the app can do free call I hated this app guys don't download the app
It is good as a free overseas phone application but sometimes It seems to be the quality of the call is bad and my voice is automatically changed. I can hear the counselor's voice change from time to time. It sounds like scared. It's a greatest free app, I'm sorry i couldn't give 5 star.. it sounds rude but it's true due to the quality of the phone.
