VoIPStunt is a program for your iPhone, Android, Mac, or PC computer, which allows you to make international free phone calls – or call at low rates. Calls to landlines and mobile phones are free in many areas – for a limited time – and once you run out of free calls over WiFi, you can buy credits for more calls at a good price.
PopTox makes it possible to call a regular cell phone or landline for free! The call recipient doesn’t need the PopTox app for you to make the free phone call. You can call from your computer or the mobile PopTox app and only need an internet connection.
This interference with VoIP app usage is motivated by the economic concerns of the UAE’s state-owned telecom companies. Since these companies, Etisalat and du, earn most of their revenue from international calls, allowing people to make free calls with calling apps would cause a major drop in their revenue.
