T-Mobile UK believes VoIP isn't sufficiently consistent or capable of providing calls of a high enough quality calls to be allowed into its mobile phone network, the carrier said to day in response to revelations it has effectively banned the technology from its latest data-oriented airtime package. However, the company did say it is considering allowing the use of instant messaging on its network "later in the year". For now, though, IM is likewise off-limits to the company's customers.

Earlier this week, Reg Hardware revealed that the terms and conditions underpinning T-Mobile UK's Web 'n' Walk Professional airtime package, which focuses on GPRS and 3G data connectivity, makes it clear VoIP and IM are not to be used.

"Use of Voice over Internet Protocol and Messaging over Internet Protocol [over the service] is prohibited by T-Mobile," the Ts&Cs read. "If use of either or both of these services is detected, T-Mobile may terminate all contracts with the customer and disconnect any SIM cards and/or Web 'n' Walk cards from the T-Mobile network."

I am not saying this is the case, but the question had to be asked. Really, what do you think?
