The support for radio standards depends on carriers and the network modules. China Mobile supports both 2G and 4G. China Telecom and China Unicom only support 4G. 1NCE supports 2G, 3G, and 4G. Besides the carrier, you must select the correct network module that supports the radio standard you want.
