US Communications giants AT&T admits to blocking 3G VoIP across the company’s network.

AT&T had to admit to the Federal Communications Commission in the States that it struck a deal to prevent VoIP calls being made across the 3G network.

VoIP calls cost mobile phone providers money, as it cuts the cost of calls for the user – calls that would usually be made with mobile minutes.

Customer voice plans would not generate the predicted revenues if VoIP calls were available.

It seems that despite this rather unfair move on the part of AT&T, it seems that without removing the ability to make VoIP calls, they will all lose money. In fact, without the revenues created by voice call plans, there would be a slow on mobile phone advancements overall.

AT&T has said that VoIP can be used on any VoIP apps that use Wi-Fi to operate, but that they would be blocked from the iPhone.
