What might have taken Apple an year an a half to allow VoIP over mobile network but it only took Fring only a couple of days to update their app to make it use for VOIP calls.As recently one of the most popular chat clients Fring for the iPhone is capable of doing voice and video calls over 3G networks.
The new iPhone/iPad SDK brought to us one very welcome detail: VoIP calls over 3G are no longer forbidden. The first company to capitalize on this change was iCall, and now another popular instant messaging/chat client, Fring, has enabled video and voice chat over a 3G connection.
To be able to use this new feature of Iphone,you have to restart Fring, and the restriction for 3G VoIP calls will be vanish. Some users may still be getting the message that “voip calls are not allowed…” If this happens, click on “More,” then “Go offline” and then reopen Fring.
