Mobile VoIP network makes a new play for iPhone users

Apple iPhone owners now have the ability to make low cost international phone calls using an existing Web-based "Virtual Mobile Network," whose proprietors hope there's a market out there for iPhone users on a budget.

Morodo's MO-Call iPhone users are able to place calls to other phone numbers using the Safari browser. Each international call is redirected through the MO-Call network, eliminating international roaming charges for mobile phone users.

Morodo aims to use the iPhone Mo-Call service as a stepping stone in the company's aim to become a global VoIP service operator. Developed using multiple mobile OS platforms, MO-Call can be used with more than 800 different mobile phones on the market, according to Morodo.

For example, a call originating from a US mobile phone to a mobile phone user in Japan will cost $0.23 per minute, while the same calls through Verizon Wireless cost phone owners $1.62 per minute. But providers such as Verizon Wireless also offer an "International Long Distance Value Plan Per Minute" rate where the call costs $0.19 if a user pays a $3.99 monthly surcharge.
