The NB-IoT Bands selected for North America are B4 (1700 MHz), B12 (700 MHz), B26 (850 MHz), B66 (1700 MHz) and B71 (600 MHz). Narrow Band IoT is a low power wide area (LPWA) technology developed specifically for IoT devices and services.

 3GPP has assigned different frequency bands in different regions for this cellular IoT standard.

NB-IoT Band	Uplink Band	Downlink Band	Bandwidth	Duplex Mode
B4	1710 -1755 MHz	2110 -2155 MHz	45 MHz	HD-FDD
B12	699 - 716 MHz	729 - 746 MHz	17 MHz	HD-FDD
B26	814 - 849 MHz	859 - 894 MHz	35 MHz	HD-FDD
B66	1710 - 1780 MHz	2110 - 2200 MHz	70/90 MHz	HD-FDD
B71	633 - 698 MHz	617 - 783 MHz	65 MHz	HD-FDD

假如B12  每个国家的频段是不一样的吧
