| I'm not sure what you mean by a WIFI SIM card. A SIM card is designed to run on a GSM network. Outside of a wifi area you would need to use some sort of network to transmit your data.. there really is no option other than a GSM/CDMA carrier. Also, we have the problem of distribution now. Microsoft doesn't have the same retail presence that Apple has. Google proved that selling handsets direct to consumers doesn't work that well. Nokia closed down their stores in NYC, Chicago and London. Think of the retail stores that T-Mobile, AT&T, Verizon, Sprint etc have across the country... there is no way to compete with that. The GSM protocol is design to handle voice data and is well optimized and uses surprisingly little bandwidth. Skype is much heavier on bandwidth in comparison. The skype protocol wasn't designed to be used as you walk through areas of low signal or for 1,000 users going through one cell phone tower at once. For simple voice data... the GSM protocol wins hands down. If you want to imagine any Microsoft/Skype/Nokia/Windows 7 mash up.. what if they adapted the Skype p2p technology for use on handsets to allow you to connect through other handsets to get to a base station? This will allow you to route around network congestion, prevent dropped calls, reduce network infrastructure and increase network coverage. Nokia makes the cell tower infrastructure through Nokia Siemens... If anyone could do this, it is Nokia. Imagine how hard carriers would push a p2p handset. </dream> |
