So my girlfriend (long distance relationship, haha) bought a Samsung Galaxy Tab 3 7.0, and we want to Skype with each other. The problem is that her tablet can't handle Skype, which makes her Skype freeze and lag all the time. So we are unable to call. Is there any alternative so we can call? (Keep in mind that I am on a PC and she is on a tablet)
Edit: It can't be the internet, since she has full wifi connection. Also, her Skype just freezes when calling, when logging in it redirects automatically to the homescreen etc.
