Sorry but, you seem to not at all understand what Flexiroam or World Phone are.
You're correct that apps like Line, Skype, Viber can all be used to make cheap/free voice/video calls through the internet. This is one option for travellers who only want to do just that.
Here are the things that both Flexiroam and World Phone are offering:
- lease foreign phone numbers to make and receive calls as a local contact number. Even receive voicemail.
- make and receive calls on the celular network of wherever you are, instead of being charged exorbitant roaming charges. Even line/ skype / viber will cost insane roaming charges unless you're connected to your hotel wifi or something.
-What do you do if someone wants to contact you when you're out and about? How about people in the country you're visiting who want to call you? You expect a taxi driver to make a booking confirmation with you by calling or texting you at your foreign number and paying for it? (This is the example that was given in the launch presentation)
Skype/viber/line are great for what they are. But unless you have free wifi or affordable 3g/4g (at decent speeds) wherever you are all the time at your travel destinations, you have to admit that they offer limited utility.
With flexiroam/ world phone, you can use those apps on your phone via the internet on the local cellular network, at a reasonable price.
These apps aren't in the same space as Line/skype/viber. Their intended application is to fill the gap of the things that those existing internet calling apps cannot do.
Theyre not competing against skype/line/viber. They're in a space of their own.
