In its latest update, the iPhone app fring which allows instant messaging and VoIP calls between users has added the ability to call people on regular landline or mobile numbers. The new feature, fringOut isn’t free but the rates are fairly competitive starting at 1c a minute for users in the US and UK and users can still call other Fring users at no cost.
Rates vary from country to country so be sure to check out the full list of rates, but the service should work from any country, but be careful to note that calls are charged in one-minute increments. The service also currently does not send SMS messages and calls cannot be made to premium, toll-free or emergency numbers.
