您的无线服务提供商可能不允许其3G网络上的服务器和服务。在技​​术方面，它很可能是你的供应商不分配一个IP地址，每一个电话，而它很可能指示查询朝其功能是作为一个NAT网关为许多手机网络上的服务器。 IP地址你试图连接到不属于您的电话，但该服务器;就像如果你试图连接到家庭路由器后面的服务器。

Your wireless provider probably does not allow servers and services on its 3G network. On the technical side, it is quite likely that your provider does not assign an IP address to every phone, rather it probably directs queries towards a server which functions as a NAT gateway for many phones on the network. The IP address you're trying to connect to wouldn't belong to your phone, but that server; just as if you were trying to connect to a server behind your home router.
