Been using callbacker for 4 years now, saved thousands of $ calling internationally over that time period!
Bad customer support

Their customer support is very bad, they can't even respond to you even if you have a serious service issues, they should work on their customer support service, until then the app is useless
Edit number

Their app is cool, good call quality, just that I mistyped my number and the app doesn’t let me edit it..
Great app for low cost international calling

This is a great application for cheapest international calling, connection timing and voice quality is awesome. I have been using this app from two years and it never ever let me down. Kindly use my invitation code 696095 for joining which we obviously reward me as well you for sure.
Saving long distance relationship ?

I used to use a different app, but it doesn’t work well once I moved from Russia to U.S., this one is also a way cheaper. I think people underestimate these apps because you call actual mobile numbers. I used to top up on the website because buying through AppStore is throwing money in the air , but now the feature disspeared.hope they will get it back. still didn’t find where to send claimed sms either. Great app otherwise
