Very good app

I just read complaints on this app, which I found myself hard to believe as I have just this app in and off for about a year. I can only speak to how I found it. Which is awesome and at the end of each call you will get a saving against just placing directly. Look, there are positives in life just as they have negatives but I haven’t found any!! Have a go you like keep you don’t like them delete it. Personally I love and since my son recommended it to me hey wants not to like?

Is this a scam?

It asked me for personal information to register, but then would not let me direct dial. It then asked me for access to my contacts.

Once I added my contacts, it claimed I wasn't registered. But the registration option is gone!!
