Customer Reviews

Worst app!!

When I first heard about this app I was happy cos I could finally make calls with my iPhone. But I've regretted downloading it. The credit runs out wayyyy too quickly. For one, most calls don't go through even when you have credit. And the one thing that pisses me off most is if you've run out of mins on your phone contract, it does not work.
I don't understand why I purchase credit on this app and yet it takes it from my phone contract minutes. That's just like charging me twice. It is ridiculous!!!
I would not recommend this app to anyone. It's a rip off!!!
I would rather send the credit from the app "Ding" to my family in Ghana for them to call me instead.


Works superbly well. Cheap calls to family and friends overseas on their overseas numbers. Perfect. Tells you how much balance you have remaining, the cost of a call per minute and how long you have left of airtime before you need to top-up again! Brilliant app.

Doesn't work any longer

Was amazing for several months, really a great solution for international calls. But now in the past two months it's kept working on and off, despite O2 saying they're working on it. Last time it wasn't working I spent time on the phone with O2, this time I'm just going to find another solution. It's a shame as it was a great app
