It is an awesome free app if you just want to use text. I purchased minutes to keep a disposable or a second line. I did not use the app for 30 days and the number was taken or whatever called. It also removed all my credits I bought and when I contacted the support, it took about 5 days to get response and was asked for the detail transaction, screen shot, email and plenty of things.
When the app was not running; I cannot accept incoming calls. It just shows answering call but the line is already dropped. 100% of the calls were as missed call.
I would not suggest anyone to buy minutes as you will loose your credits if you dont use your "Text". I am not a fan of texting as it lacks personal interaction and take forever to have the conversation. I will not buy minutes until last minute I am going to use it.
