VoIP: How the Internet affects mobile phone companies
Thursday 21 June 2007 09:41:17 by Sebastien Lahtinen

Mobile phone operators have been launching new Internet services for quite some time with Vodafone recently announcing a reduction in its data tariffs earlier this week, but this increase is causing real problems as the tools are becoming available for users to route their voice calls through the Internet, and thus avoid incurring expensive mobile phone charges. This has resulted in mobile service providers restricting use of 'VoIP' services in a number of ways.

Truphone ( has raised concerns about their interconnection with T-Mobile which prevents their customers from receiving calls from T-Mobile telephone numbers by refusing to sign an interconnect agreement on terms which would be fair to Truphone for their new 07978 number range. The company

"T-Mobile will argue that it is not 'blocking' Truphone but is merely negotiating on price. T-Mobile receives 35p per minute from its customers but is offering only 0.21p per minute to Truphone even when Truphone's costs are 9p per minute to terminate the call. T-Mobile is blocking our numbers unless we accept this loss-making offer and, since T-Mobile is the only company that can route calls from its customers it has a complete veto on the Truphone service."

Vodafone and Orange have previously disabled VoIP functionality from the Nokia N95 on their own firmware, although one has to ask the question, if the mobile operators are subsidising the phones based on your use of their services, if you want to use a VoIP service, should the VoIP provider be providing you with a suitable phone?

The mobile networks killer app is voice, as proven by Three, so it is natural that they want to protect revenues from calls. At least one of the providers has a higher priced data account that includes VoIP whereas the cheaper one excludes it.

Hi, Net Neutrality v2.0

its not really a net neutrality issue, mobile phone networks are WANs not the internet so they can choose what services to offer or not.

I'm slightly concerned that the largest player in the new mVOIP market is actually pretty inadequate.

In my opinion it's worth checking out, another mVoip start-up who have actually been bothered to make their own software. It's called onefone, and it's vastly superior.
