推荐答案

无法在代码中的2G和3G之间进行更改，电话硬件会根据网络可用性做出决定.
如果考虑一下，如果您具有此选项，则可以将电话从3G强制转换为2G，这也将迫使语音流量进入2G网络.

在代码之外，唯一的选择是获取未启用3G访问的SIM卡，这会将手机限制在启用了该功能的任何网络上.

There is no option to change between 2G and 3G in code, the phone hardware makes the decision based on network availability.
If you think about it, if you had this option to force a phone from 3G to 2G that would also force voice traffic onto the 2G network.

Outside of code the only option is to get a SIM card that is not enabled for 3G access that will restrict the phone to whatever network it is enabled for.
