You pay for the calls you make using Dial-a-Code in exactly the same way as you pay for the regular calls you make from your mobile. PAY MONTHLY CUSTOMERS will see calls to Dial-a-Code's 6 digit access code starting '29' listed on their itemised bill. PAY AS YOU GO customers will see the cost of their call deducted from their call credit.

Upgrade is a downgrade

This was a great international call App until the recent changes removed the function of searching your address book. It’s now become far to time consuming to use and is a hinderance rather than a useful tool. What on Earth has happened...!!!?

Don’t think this app is still working

I am sure you are aware that this App do
Not work anymore and you’re still charging people for trying to use it. I used to use it to make international calls, especially to Nigeria and I thought it was network issue for awhile until I realised that this couldn’t be just network because even sometimes you have not paid for your own connection and we get that message went we try to make a call. I had to go and check recent reviews and I saw that a lot of people are complaining and even deleting the app.
I wonder why you would develop this fantastic app and refuse to maintain. I hope you realise that this free money you’re getting is just for awhile people would keep leaving and deleting your app since it’s not working and it’s just a matter of time before it would all end.

Won’t work anymore

This app was fantastic and let me call NZ from the UK at very reasonable rates. But it hasn’t worked now for around 3 months, keeps saying the numbers I’m calling can’t be reached. I know this isn’t true as I can connect without the app, albeit for an exorbitant price. Please could you fix the service? I have elderly sick family at home who I need to contact regularly, and it’s costing me a fortune without this app!
