VoIP-Over-Cellular: Read the Fine Print
John Blau writes on InfoWorld:
As low-priced Internet phone services for mobile devices emerge, users should first check the fine print in their cell phone contracts to see if they can take advantage of such services.More here.
There's a chance they can't.
T-Mobile International AG & Co. KG, which has mobile phone operations in Europe and the U.S., is among the first companies to ban the use of VOIP (voice over Internet Protocol) service over its networks. Its Web 'n' Walk professional service expressly prohibits such usage and reserves the right to terminate contracts.

The author should look more closely at the T-mobile conditions and how Mino works.
T-mobile prohibits "streaming" content and VOIP over the data service. But it turns out than Mino does not use the data leg for voice at all. The data leg is used to setup the calls, but the actual audio is 100% standard cell analog. Mino claims that 1.2K is used for call setup, regardless of call length.
This is no different than calling your office PBX and then calling outbound internationally. By integrating this into the phone's OS with Java, Mino has an excellent opportunity that does not violate any of T-mobile's data terms, mostly because the data stream is not used for the call.
