Apple has given up blocking voice-over-IP (VoIP) calls over 3G data networks on the iPhone, and has changed the SDK to reflect the allowance. Of course, carrier has to also comply for VoIP calls to work over 3G in addition to Wi-Fi. AT&T in the U.S. is already on board.
By using VoIP applications to sidestep the phone’s normal calling software, iPhone owners could avoid using up their monthly allocation of minutes from AT&T, potentially allowing them to choose cheaper plans.
“Fring users and our team alike are very excited that Apple has allowed independent Iphone VoIP applications over 3G networks, letting users make voice and video calls over whichever Internet access suits their needs at any given place and time,” said Avi Shechter, cofounder and CEO of Fring.
AT&T announced last October that it would allow VoIP-over-3G service. After that announcement, an Apple spokeswoman told Cnet that Cupertino was “very happy” with AT&T’s decision and that they would update its developer agreements to allow VoIP-over-3G support “as soon as possible.”
A company called iCall Inc. said its app was the first to be approved by Apple. iPhone users can download the app and pay $10 for unlimited phone calls. Or they can choose iCall’s free option, in which calls are limited to five minutes and users must listen to advertisements at the beginning of the call.
