It’s a SCAM! Does NOT WORK and is NOT FREE!

Bought this app to try it but it’s not free as it claims. You can’t make a call without buying credits and when I bought credits I found out it doesn’t work at all. Simply disconnects right away. SCAM!!!


absolutely trash

this app call you to verify who you are and don't even work with any buttons and you need to waste of your 2 minutes to listen them and the app is not working at all. this app is trash



My grandparents don't use smart phones, but I can still call them often with this app. I think this is the most outstanding feature compared to other international call apps.
