T-Mobile says mobile VoIP will not hit revenues
I see no ships
3GSM Mobile VoIP (voice over internet protocol) will not hit mobile telephony revenues, but will have more of an impact on fixed line services, according to T-Mobile International AG chief executive Hamid Akhavan.
Akhavan said mobile VoIP would only take "a small share" of mobile revenues.
He said takeup of the technology would be hampered by technical issues, the need for constant connections, and problems with emergency numbers.

His words may seem at odds with predictions from many at the 3GSM show in Barcelona, but they were supported by Thus, which questioned whether the technology is mature enough for business use.
Mark Charlesworth, head of messaging, mobility and applications at Thus, said: "The overall user experience with VoFi phones has always been questionable. The more applications made available on the handsets the more electricity they require. VoFi handsets are notorious consumers of power and their battery life is much shorter than handsets launched for other specifications - a major practical drawback to using them for business applications.
"The quality of the actual call has also been a consideration with Wi-Fi access. This is because the VoFi phone is sharing the available bandwidth with all other Wi-Fi traffic." ®
