Visit our article on how to Secretly Spy on Someone's Cell Phone for more details on the things you need to consider before installing a spy phone app. Honestly, people who cheat are like people who collect cars, candles, little statues, or anything else.
In addition, Google Voice does not receive some verification calls (I need to log into a VPN via a phone call for my work); as such, I use Skype for this call.
Thankfully most of my friends and family use i OS, so I can use i Message.
The regular Google Hangouts Web app is pretty impressive, too.
On your smartphone, this works over data (or Wi-Fi if you’re connected), so calls over Hangouts do not use any of your included minutes.
I suspect that my girlfriend is still cheating on me after I found out when I borrowed her phone and checked her Facebook, Skype and Viber, we had an argument, now she's saying that she is not cheating anymore but I can't believe it because she won't let me check her phone ever and she's using a code I can never check it even if I get the chance to.
