I wish it possible i won’t even give your app any star.

I want my money back, you should please take your number back, because I don’t get people text, it just a big waste for me. This is a big mess, my text are delivering to my friend but I can’t get their text. That a big rubbish and wasting of money... anyone who is about to use this app, just don’t waste your money, if your friends don’t have the app, and text you from the app, no way they can get your messages unless they call you that all. For anyone who is in the United state and buying purchasing +1 number. I so hate why I just wasted money for 3 month. If possible please refund my money back, I don’t need your number anymore, as I can’t get people text only their call and my text is going through.


pretty good

I just started my business on eBay and I hate giving my Personal phone number out or having to buy a Prepaid phone but with this app, everything is convenient and easy. Gives me a 2nd number with good price. No complaints



Excellent software for calling to any country. The call quality and customer support is superb. Anytime anywhere I can call and it works as if I am calling directly to my friends. You can easily manage your contact list by Country or group. Very powerful
