Ever needed to make a cheap international call without the internet, or been worried about security as you move between wifi hotspots? These apps make travel safer, easier and cheaper
Skype and Whatsapp will always be staples when it comes to international calling and messaging, but a wifi connection is needed to use them. To make cheap calls around the world without the internet (or faffing around with phonecards), the app to choose is Rebtel. By “hijacking” local phonelines, it gets the best available calling rates. Recently launched, it is currently offering a “Rebel calling” deal, which means friends or family can be called for free if they are also using the app (until 2018).
