Skip to main content rolls out free data & Wi-Fi voice calling to iOS app

Instant messaging platform has announced an update to its iOS app, which will bring voice calling to users over Wi-Fi or mobile data connections.

The feature rolled out to Android users in February, providing free phone calls without gobbling up any mobile minutes. To make calls on your iPhone, simply tap the phone icon next to your contact's name.

Today's launch is "perfect timing," the announcement said, "given that mobile carriers are constantly changing plans and services, making it quite tricky for the average user to save money."

"The availability of free voice calling for iPhone users is a critical development for users looking to keep those valuable lines of communication open while saving on their mobile costs," CEO Ralph Harik said in a statement.

As TechCrunch pointed out, however, seems a bit late to the game, running behind competitors like Viber and Nimbuzz, who already offer voice calls. Still, the company touted its ability to provide messages from various services, including Skype, Facebook Chat, and Google Talk, in just one app.

"At, our mission has always been to provide one place for family and friends to stay connected and maintain their close relationships no matter where they are located," Harik said.

In April, imo got a facelift when its updated UI added location sharing and other features. It now supports 12 different IM services, and carries improved Web content viewing and a profile management screen.

In a world where Facebook and Twitter reign over popular media discussions, imo has gained more than four million mobile downloads and claims 700,000 daily users delivering an average of 50 million messages per day, according to a press release.

The communications app offers group chat, video chat, voice IMs, and multimedia sharing.

The imo instant messenger app is currently available for download in Apple's App Store and the Google Play store. iPhone users running iOS 3.1 or higher can now make voice calls through the app.
