As German teltarif.de reports, T-Mobile UK has said it definitely prohibits the use of VoIP and Instant Messenger applications over its Web 'n' Walk Professional mobile Internet access package. The T-Mobile UK web site declares "Use of Voice over Internet Protocol and Messaging over Internet Protocol is prohibited by T-Mobile. 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."
In a conversation with ZDNet, Robert Langton, T-Mobile UK's data marketing manager, stated "It's a commercial decision that we took. We charge two and a half times less than our competition. We're aiming at the business network. We spoke to our customers and it's not key to them."
Pardon me? What? Prohibiting IM over web'n'walk? What's that? I mean is T-Mobile UK selling Windows Mobile devices in the UK which includes MSN Messenger (unlike Orange)? If so, how can it be wrong to use a service *which is preinstalled* on a T-Mobile labeled MDA or SDA?
However, it becomes even worse. According to Langton, T-Mobile could allow IM over the T-Mobile network, if enough customers requests it. "However, in this case it could be T-Mobile messaging client".
Looks like also UK T-Mobile users can slightly say good bye to MSN Messenger on Windows Mobile devices and it sounds not to be a good idea at all to install and use Skype or similar services on the devices, while connected to T-Mobile.
