I tried these free VoIP Android Apps that operates on Google Voice: Talkatone and GrooVe IP Lite.
Then, I paid and tried the GrooVe IP. What a waste of money.
All are not much better particularly on audio clarity.
That is why I just wish to test Spare Phone. However, this is the most expensive app.
I just want to test it. If its any good, I am willing to pay for it.
Google show this Clearfile.com link. It just loop and make you do hoops and never download. I assume it scam.
Well, cannot get to even test the older version apk of Space Phone.
Should I give up?
